This makes a strong case for logging the messages from the VPN concentrator. On Cisco firewall devices, the console port is an asynchronous line that can be. Held/Resumed, Transferred And Parked Calls Will Also Be Recorded. AnyConnect includes the profile editor as part of ASDM and as a stand-alone Windows program. To add a new client profile to the ASA from. USER MANUAL FILEZILLA
Any entries put in that Backup Server location are overwritten with what is entered here for an individual server list entry. This setting takes precedence and is the recommended practice. If the host for this server list entry specifies a load balancing cluster of security appliances, and the Always-On feature is enabled, add the load balancing devices in the cluster to this list. If you do not, Always-On blocks access to the devices in the load balancing cluster.
If you specify IPsec, the User Group must be the exact name of the connection profile tunnel group. For SSL, the user group is the group-url or group-alias of the connection profile. Changing the authentication method from the proprietary AnyConnect EAP to a standards-based method disables the ability of the ASA to configure session timeout, idle timeout, disconnected timeout, split tunneling, split DNS, MSIE proxy configuration, and other features.
When the user clicks Get Certificate , the client prompts the user for a username and one-time password. Enter the certificate thumbprint of the CA. Click OK. SBL also includes the Network Access Manager tile and allows connections using user configured home network profiles. Network profiles allowed in SBL mode include all media types employing non PLAP supports bit and bit versions of the Windows. A user has network-mapped drives that require authentication with the Microsoft Active Directory infrastructure.
The user cannot have cached credentials on the computer the group policy disallows cached credentials. In this scenario, users must be able to communicate with a domain controller on the corporate network for their credentials to be validated before gaining access to the computer.
The user must run logon scripts that execute from a network resource or need access to a network resource. With SBL enabled, the user has access to the local infrastructure and logon scripts that would normally run when a user is in the office. This includes domain logon scripts, group policy objects and other Active Directory functionality that normally occurs when users log on to their system.
AnyConnect is not compatible with fast user switching. AnyConnect cannot be started by third-party Start Before Logon applications. Because SBL is pre-login and will not have access to the user store, you cannot do multiple certificate authentication MCA with it. MCA requires a machine certificate and a user certificate, or two user certificates. On Windows 7, or the Windows server, the installer determines whether the bit or bit version of the operating system is in use and installs the appropriate PLAP component, vpnplap.
When predeploying AnyConnect, the Start Before Logon module requires that the core client software is installed first. Select a group policy and click Edit or Add a new group policy. SBL requires a network connection to be present at the time it is invoked.
In some cases, this might not be possible, because a wireless connection might depend on credentials of the user to connect to the wireless infrastructure. Since SBL mode precedes the credential phase of a logon, a connection would not be available in this scenario. In this case, the wireless connection needs to be configured to cache the credentials across logon, or another wireless authentication needs to be configured, for SBL to work.
If the Network Access Manager is installed, you must deploy device connection to ensure that an appropriate connection is available. Select Use Start Before Logon. The user must reboot the remote computer before SBL takes effect. Reboot the computer and retest. Browse back to the security appliance to install AnyConnect again. Reboot once. On the next reboot, you should be prompted with the Start Before Logon prompt.
Go back to the. Auto Connect On Start is disabled by default, requiring the user to specify or select a secure gateway. Select Auto Connect On Start. This ensures that users connect to their corporate infrastructure before logging on to their computers. This feature lets programmatic network administrators perform specific tasks, such as collecting credentials or connecting to network resources before logon.
PLAP supports bit and bit versions of the operating system with vpnplap. The PLAP functions supports x86 and x When Auto Reconnect is enabled default , AnyConnect recovers from VPN session disruptions and reestablishes a session, regardless of the media used for the initial connection.
For example, it can reestablish a session on wired, wireless, or 3G. When Auto Reconnect is enabled, you also specify the reconnect behavior upon system suspend or system resume. If you disable Auto Reconnect, the client does not attempt to reconnect regardless of the cause of the disconnection. Cisco highly recommends using the default setting enabled for this feature. Disabling this setting can cause interruptions in VPN connectivity over unstable connections.
Select Auto Reconnect. Disconnect On Suspend— Default AnyConnect releases the resources assigned to the VPN session upon a system suspend and does not attempt to reconnect after the system resume. Reconnect After Resume—The client retains resources assigned to the VPN session during a system suspend and attempts to reconnect after the system resume. Trusted Network Detection TND gives you the ability to have AnyConnect automatically disconnect a VPN connection when the user is inside the corporate network the trusted network and start the VPN connection when the user is outside the corporate network the untrusted network.
It does not disconnect a VPN connection that the user starts manually in the trusted network. TND only disconnects the VPN session if the user first connects in an untrusted network and moves into a trusted network. No changes are required to the ASA configuration. You need to specify the action or policy AnyConnect takes when recognizing it is transitioning between trusted and untrusted networks, and identify your trusted networks and servers. Multiple profiles on a user computer may present problems if the TND configuration is different.
If the user has received a TND-enabled profile in the past, upon system restart, AnyConnect attempts to connect to the security appliance it was last connected to, which may not be the behavior you desire. To connect to a different security appliance, they must manually disconnect and re-connect to that headend.
The following workarounds will help you prevent this problem:. If users do not need to have multiple, different profiles, use the same profile name for the profiles on all the ASAs. Each ASA overrides the existing profile. Choose a Trusted Network Policy. This is the action the client takes when the user is inside the corporate network the trusted network. The options are:.
Connect—The client starts a VPN connection in the trusted network. Do Nothing—The client takes no action in the trusted network. Pause—AnyConnect suspends the VPN session instead of disconnecting it if a user enters a network configured as trusted after establishing a VPN session outside the trusted network. When the user goes outside the trusted network again, AnyConnect resumes the session. Choose an Untrusted Network Policy.
This is the action the client takes when the user is outside the corporate network. Connect—The client starts a VPN connection upon the detection of an untrusted network. Do Nothing—The client takes no action upon detection of an untrusted network. Specify the DNS suffixes a string separated by commas that a network interface may have when the client is in the trusted network. The split-DNS suffix list passed by the head end. All DNS server addresses a string separated by commas that a network interface may have when the client is in the trusted network.
For example: If mus. Specify a host URL that you want to add as trusted. You must have a secure web server that is accessible with a trusted certificate to be considered trusted. After you click Add , the URL is added and the certificate hash is pre-filled. If the hash is not found, an error message prompts the user to enter the certificate hash manually and click Set.
Always-On operation prevents access to Internet resources when the computer is not on a trusted network, unless a VPN session is active. Enforcing the VPN to always be on in this situation protects the computer from security threats.
When Always-On is enabled, it establishes a VPN session automatically after the user logs in and upon detection of an untrusted network. The VPN session remains open until the user logs out of the computer, or the session timer or idle session timer specified in the ASA group policy expires. AnyConnect continually attempts to reestablish the connection to reactivate the session if it is still open; otherwise, it continually attempts to establish a new VPN session.
The following AnyConnect options also need to be considered when enabling Always-On :. Pressing the disconnect button locks all interfaces to prevent data from leaking out and to protect the computer from internet access except for establishing a VPN session. Users of Always-On VPN sessions may want to click Disconnect so they can choose an alternative secure gateway due to performance issues with the current VPN session, or reconnection issues following the interruption of a VPN session.
See Set a Connect Failure Policy. AnyConnect starts the VPN connection only post-login. Always-On VPN does not support connecting though a proxy. To enhance protection against threats, we recommend the following additional protective measures if you configure Always-On VPN:.
We strongly recommend purchasing a digital certificate from a certificate authority CA and enrolling it on the secure gateways. Predeploy a profile configured with Always-On to the endpoints to limit connectivity to the pre-defined ASAs. Predeployment prevents contact with a rogue server. Restrict administrator rights so that users cannot terminate processes.
A PC user with admin rights can bypass an Always-On policy by stopping the agent. If you want to ensure fully-secure Always-On , you must deny local admin rights to users. Users with limited or standard privileges may sometimes have write access to their program data folders. They could use this access to delete the AnyConnect profile file and thereby circumvent the Always-On feature.
Predeploy equivalent measures for macOS users. Always-On VPN requires that a valid, trusted server certificate be configured on the ASA; otherwise, it fails and logs an event indicating the certificate is invalid. Select Always On. Optional Configure a Connect Failure Policy. Optional Configure Captive Portal Remediation. With Always-On VPN disabled, when the client connects to a primary device within a load balancing cluster, the client complies with a redirection from the primary device to any of the backup cluster members.
With Always-On enabled, the client does not comply with a redirection from the primary device unless the address of the backup cluster member is specified in the server list of the client profile. Therefore, be sure to add any backup cluster members to the server list. To specify the addresses of backup cluster members in the client profile, use ASDM to add a load-balancing backup server list by following these steps:.
Choose a server that is a primary device of a load-balancing cluster and click Edit. You can configure exemptions to override an Always-On policy. For example, you might want to let certain individuals establish VPN sessions with other companies or exempt the Always-On policy for noncorporate assets. Exemptions set in group policies and dynamic access policies on the ASA override the Always-On policy.
You specify exceptions according to the matching criteria used to assign the policy. If an AnyConnect policy enables Always-On and a dynamic access policy or group policy disables it, the client retains the disable setting for the current and future VPN sessions as long as its criteria match the dynamic access policy or group policy on the establishment of each new session. This procedure configures a dynamic access policy that uses AAA endpoint criteria to match sessions to noncorporate assets.
This can occur when a secure gateway is unreachable, or when AnyConnect fails to detect the presence of a captive portal hotspot. An open policy permits full network access, letting users continue to perform tasks where access to the Internet or other local network resources is needed. A closed policy disables all network connectivity until the VPN session is established. AnyConnect does this by enabling packet filters that block all traffic from the endpoint that is not bound for a secure gateway to which the computer is allowed to connect.
Regardless of the connect failure policy, AnyConnect continues to try to establish the VPN connection. Consider the following when using an open policy which permits full network access:. Security and protection are not available until the VPN session is established; therefore, the endpoint device may get infected with web-based malware or sensitive data may leak. An open connect failure policy does not apply if you enable the Disconnect button and the user clicks Disconnect. Consider the following when using a closed policy which disables all network connectivity until the VPN session is established:.
A closed policy can halt productivity if users require Internet access outside the VPN. The purpose of closed is to help protect corporate assets from network threats when resources in the private network that protect the endpoint are not available. The endpoint is protected from web-based malware and sensitive data leakage at all times because all network access is prevented except for local resources such as printers and tethered devices permitted by split tunneling.
This option is primarily for organizations where security persistence is a greater concern than always-available network access. A closed policy prevents captive portal remediation unless you specifically enable it. For example, these rules could determine access to active sync and local printing. The network is unblocked and open during an AnyConnect software upgrade when Always-On is enabled regardless of a closed policy.
If you deploy a closed connection policy, we highly recommend that you follow a phased approach. For example, first deploy Always-On with a connect failure open policy and survey users for the frequency with which AnyConnect does not connect seamlessly. Then deploy a small pilot deployment of a connect failure closed policy among early-adopter users and solicit their feedback.
Expand the pilot program gradually while continuing to solicit feedback before considering a full deployment. As you deploy a connect failure closed policy, be sure to educate the VPN users about the network access limitation as well as the advantages of a connect failure closed policy. A connect failure closed policy prevents network access if AnyConnect fails to establish a VPN session. Use extreme caution when implementing a connect failure closed policy.
By default, the connect failure policy is closed, preventing Internet access if the VPN is unreachable. To allow Internet access in this situation the connect failure policy must be set to open. Set the Connect Failure Policy parameter to one of the following settings:. Closed— Default Restricts network access when the secure gateway is unreachable. Open—Permits network access by browsers and other applications when the client cannot connect to the secure gateway. Configure Captive Portal Remediation.
Many facilities that offer Wi-Fi and wired access, such as airports, coffee shops, and hotels, require the user to pay before obtaining access, to agree to abide by an acceptable use policy, or both. These facilities use a technique called captive portal to prevent applications from connecting until the user opens a browser and accepts the conditions for access.
Captive portal detection is the recognition of this restriction, and captive portal remediation is the process of satisfying the requirements of a captive portal hotspot in order to obtain network access. Captive portals are detected automatically by AnyConnect when initiating a VPN connection requiring no additional configuration. Also, AnyConnect does not modify any browser configuration settings during captive portal detection and does not automatically remediate the captive portal.
It relies on the end user to perform the remediation. AnyConnect reacts to the detection of a captive portal depending on the current configuration:. If Always-On is disabled, or if Always-On is enabled and the Connect Failure Policy is open, the following message is displayed on each connection attempt:.
The end user must perform captive portal remediation by meeting the requirements of the provider of the hotspot. These requirements could be paying a fee to access the network, signing an acceptable use policy, both, or some other requirement defined by the provider.
If Always-On is enabled and the connect failure policy is closed, captive portal remediation needs to be explicitly enabled. If enabled, the end user can perform remediation as described above. If disabled, the following message is displayed upon each connection attempt, and the VPN cannot be connected. You configure captive portal remediation only when the Always-On feature is enabled and the Connect Failure Policy is set to closed. In this situation, configuring captive portal remediation allows AnyConnect to connect to the VPN when a captive portal is preventing it from doing so.
Configuration of captive portal remediation is not applicable to Linux, since Always On is not supported on this platform. Therefore, regardless of the Allow Captive Portal Remediation Always On setting in the profile editor, the Linux user can remediate a captive portal. If the Connect Failure Policy is set to open or Always-On is not enabled, your users are not restricted from network access and are capable of remediating a captive portal without any specific configuration in the AnyConnect VPN client profile.
By default, captive portal remediation is disabled on platforms supporting Always on Windows and macOS to provide the greatest security. AnyConnect does not provide data leakage protection capabilities during the captive portal remediation phase. If data loss protection is desired, you should employ a relevant endpoint security product.
Select Allow Captive Portal Remediation. This setting lifts the network access restrictions imposed by the closed connect failure policy. Enter the number of minutes for which AnyConnect lifts the network access restrictions. The user needs enough time to satisfy the captive portal requirements. With enhanced captive portal remediation, an AnyConnect embedded browser is used for remediation, whenever captive portal is detected with network access restricted by AnyConnect for example, due to Always On.
Other applications remain with network access blocked while captive portal remediation with the AnyConnect browser is pending. The user can close the AnyConnect browser and fail over to an external browser when enabled in the profile , causing AnyConnect to revert to the regular captive portal remediation behavior.
In doing so, the following message is shown:. You may want to set browser failover to apply whenever the AnyConnect browser is launched for captive portal remediation. By setting the browser failover, users can remediate the captive portal via an external browser, after closing the AnyConnect browser. The AnyConnect browser launched for captive portal remediation has tighter security settings with regard to server security certificates.
Untrusted server certificates are not accepted during the captive portal remediation. If untrusted server certificates are acceptable during captive portal remediation, you should enable captive portal remediation browser failover in order to allow the user to remediate the captive portal. After enabling, the user can close the AnyConnect browser and continue remediation with an external browser as AnyConnect reverts to the regular captive portal remediation behavior. Check Captive Portal Remediation Browser Failover if you want the end user to use an external browser after closing the AnyConnect browser for captive portal remediation.
The default is for the end user to only remediate a captive portal with the AnyConnect browser; that is, the user is unable to disable the enhanced captive portal remediation. AnyConnect can falsely assume that it is in a captive portal in the following situations. To prevent this, make sure the ASA certificate is properly configured.
This situation can occur when a user is on an internal network, and connects through a firewall to connect to the ASA. If users cannot access a captive portal remediation page, ask them to try the following:. Terminate any applications that use HTTP, such as instant messaging programs, e-mail clients, IP phone clients, and all but one browser to perform the remediation. The captive portal may be actively inhibiting DoS attacks by ignoring repetitive attempts to connect, causing them to time out on the client end.
The attempt by many applications to make HTTP connections exacerbates this problem. Disable and re-enable the network interface. This action triggers a captive portal detection retry. To send traffic destined for the secure gateway over a Point-to-Point Protocol PPP connection, AnyConnect uses the point-to-point adapter generated by the external tunnel. Choose a PPP Exclusion method. Also, check User Controllable for this field to let users view and change this setting:.
Automatic—Enables PPP exclusion. If automatic detection does not work and you configured the PPP Exclusion fields as user controllable, the user can override the setting by editing the AnyConnect preferences file on the local computer. Use an editor such as Notepad to open the preferences XML file. For example,.
The address must be a well-formed IPv4 address. For example:. A management VPN tunnel ensures connectivity to the corporate network whenever the client system is powered up, not just when a VPN connection is established by the end user. You can perform patch management on out-of-the-office endpoints, especially devices that are infrequently connected by the user, via VPN, to the office network. Endpoint OS login scripts which require corporate network connectivity will also benefit from this feature.
The management VPN tunnel is meant to be transparent to the end user; therefore, network traffic initiated by user applications is not impacted, by default, but instead directed outside the management VPN tunnel. When a management tunnel feature is detected as enabled, a restricted user account ciscoacvpnuser is created to enforce the principle of least privilege. This account gets removed during AnyConnect uninstallation or during an installation upgrade.
If a user complains of slow logins, it may be an indication that the management tunnel was not configured appropriately. Configure the Management VPN Tunnel describes the configuration steps that are required to enable the feature. If symptoms suggest lack of connectivity to the corporate network despite following this configuration, refer to Troubleshooting Management VPN Tunnel Connectivity Issues. Connects whenever the user initiated VPN tunnel is disconnected, before or after user login.
Requires split include tunneling configuration, by default, to avoid impacting user initiated network communication since the management VPN tunnel is meant to be transparent to the end user. Performs strict certificate checking on server certificate. The server certificate's root CA certificate must reside in the machine certificate store computer certificate store on Windows, or system keychain or system file certificate store on macOS. Currently available only on Windows and macOS.
Linux support will be added in subsequent releases. The management VPN profile does not support the value Native for proxy settings. This restriction applies only to Windows client, since the management VPN tunnel can be initiated without any user logged in; therefore, it cannot rely on user-specific browser proxy settings. Since the management VPN tunnel is meant to be transparent to the end user, user-specific or system proxy settings are not altered.
However, you can configure the group policy for the management tunnel connection to tunnel all traffic, ensuring that no traffic is leaked by physical interfaces while the user VPN tunnel is inactive. Captive portal remediation is only performed when the AnyConnect UI is running and while the user is logged in, as if the management VPN tunnel feature was not enabled. For a consistent user experience, you must use identical TND settings in both user and management VPN tunnel profiles.
Certain profile perferences are mandatory while the management VPN tunnel is active. During a management tunnel connection, the following preference values are overridden, mostly to eliminate user interaction and to minimize tunnel interruptions:. AllowManualHostInput: false —Not relevant to the management tunnel headless client.
AlwaysOn: false —Not relevant, since user tunnel profile preferences are enforced whenever the management tunnel is disconnected. AutoConnectOnStart: false —Relevant only to a UI client, for automatic connection on start-up to the previously connected host. AutomaticCertSelection: true —To avoid certificate selection popups. AutoReconnect: true —To avoid management tunnel termination on network changes.
AutoUpdate: false —No software updates are performed during a management tunnel connection. BlockUntrustedServers: true —To avoid untrusted server certificate prompts. CertificateStore: MachineStore —Management tunnel authentication should also succeed without a logged in user. CertificateStoreOverride: true —Required for machine certificate authentication on Windows. MinimizeOnConnect:false —Not relevant to the management tunnel headless client. ShowPreConnect Message —Not relevant to the management tunnel headless client.
UserEnforcement: AnyUser —To ensure that the management tunnel is not potentially disconnected when a certain user logs in. Because the management tunnel connection may occur without any user logged in, only machine store certificate authentication is supported. Consequently, at least one relevant client certificate needs to be available in the client host's machine certificate store.
Configure a Custom Attribute to Support Tunnel-All Configuration describes how to enable support for other split tunneling configurations. If a client address assignment is not configured in the tunnel group for both IP protocols, you must enable Client Bypass Protocol in the group policy, so that traffic matching the IP protocol without client address assignment is not disrupted by the management VPN tunnel. You can deploy only one management VPN profile to a given client device.
To automatically disable the feature upon profile update during tunnel establishment , you should configure zero host entries in the management VPN profile. Similarly, you may also add the management VPN profile to the group policy mapped to the regular tunnel group, used for the user tunnel connection. When the user connects, the management VPN profile is downloaded, along with the user VPN profile already mapped to the group policy, enabling the management VPN tunnel feature.
Management VPN tunnel requires split include tunneling configuration, by default, to avoid impacting user initiated network communication since management VPN tunnel is meant to be transparent to the end user. If you set a new custom attribute type to ManagementTunnelAllAllowed and set the corresponding custom attributes to true, AnyConnect proceeds with the management tunnel connection, if the configuration is one of tunnel-all, split-exclude, split-include, or bypass for both IP protocols.
For example, if management VPN profile updates re allowed only from the VPN server TrustedServer, the checkbox would be unchecked, and TrustedServer would be added to the trusted server list. If the client host is not reachable remotely, various scenarios may have occurred causing the management VPN tunnel to disconnect or not be established.
Disconnected trusted network —TND detected a trusted network so the management tunnel is not established. Disconnected user tunnel active —A user tunnel is currently pending thus disconnecting the management tunnel. Disconnected process launch failed —A process launch failure was encountered upon attempting the management tunnel connection. Disconnected connect failed —A connection failure was encountered upon establishing the management tunnel.
Disconnected invalid VPN configuration —An invalid split tunneling configuration was encountered upon management tunnel establishment. Diconnected software update pending —An AnyConnect software update is currently pending thus disconnecting the management tunnel. Disconnected—The management tunnel is about to be established or could not be established for some other reason. To troubleshoot the lack of connectivity over the management VPN tunnel expected to be established on the client host , verify the following:.
If the management connection state is unexpectedly listed as "disconnected" and the provided explanation is insufficient, capture the AnyConnect logs with the DART tool for further troubleshooting. If you see Management Connection State: Disconnected disabled in the UI stats line, ensure that the management VPN profile is configured with a single host entry, pointing to a tunnel group set up with certificate authentication.
The associated group policy must have a single profile configured: the management VPN profile. The associated group policy should have no banner enabled. User interaction is not supported during a management tunnel connection. If you see Management Connection State: Disconnected disabled in the UI stats line, ensure that the management VPN profile is configured within the group policy that is associated with the tunnel group used for regular user tunnel connections.
When the user connects with that tunnel group, the management VPN profile is downloaded, and the feature is enabled. Alternatively, you can deploy the management VPN profile out of band. If you see Management Connection State: Disconnected connect failed in the UI stats line, note that the management tunnel connection fails whenever user interaction is needed, as follows:.
The server certificate's root CA certificate must reside in the machine certificate store. The client certificate is not usable because the user cannot be prompted for the private key password. A local proxy runs on the same PC as AnyConnect, and is sometimes used as a transparent proxy. Some examples of a transparent proxy service include acceleration software provided by some wireless data cards, or a network component on some antivirus software, such as Kaspersky.
Public proxies are usually used to anonymize web traffic. When Windows is configured to use a public proxy, AnyConnect uses that connection. Public proxy is supported on macOS and Linux for both native and override.
Configuring a public proxy is described in Public Proxy. Private proxy servers are used on a corporate network to prevent corporate users from accessing certain Web sites based on corporate usage policies, for example, pornography, gambling, or gaming sites. You configure a group policy to download private proxy settings to the browser after the tunnel is established. The settings return to their original state after the VPN session ends. See Configure a Private Proxy Connection.
AnyConnect SBL connections through a proxy server are dependent on the Windows operating system version and system machine configuration or other third-party proxy software capabilities; therefore, refer to system wide proxy settings as provided by Microsoft or whatever third-party proxy application you use. The VPN Client profile can block or redirect the client system's proxy connection.
For Windows and Linux, you can configure, or you can allow the user to configure, the address of a public proxy server. Some versions of the ASA require AnyConnect configuration to support clientless portal access through a proxy server after establishing an AnyConnect session.
AnyConnect uses a proxy auto-configuration PAC file to modify the client-side proxy settings to let this occur. AnyConnect generates this file only if the ASA does not specify private-side proxy settings. OS support of proxy connections varies as shown:. Connecting through a proxy is not supported with the Always-On feature enabled.
Select default or unselect Allow Local Proxy Connections. Local proxy is disabled by default. Public proxies are supported on Windows and Linux platforms. Proxy servers are chosen based on preferences set in the client profile. In case of proxy override, AnyConnect extracts proxy servers from the profile.
With release 4. On Linux, native-proxy settings are exported before AnyConnect runs. If you change the settings, a restart must happen. Authenticating Proxy Servers requires a username and password. AnyConnect dialogs manage the authentication process. After successfully authenticating to the proxy server, AnyConnect prompts for the ASA username and password.
Follow these steps to configure a public proxy connection on Windows. Go to system preferences and choose the appropriate interface on which you are connected. Click Advanced. Choose Proxies tab from the new window. Enter the proxy server address in the Secure Proxy Server field on the right panel.
To configure a public proxy connection in Linux, you must set an environment variable. Configure the private proxy information in the ASA group policy. In a macOS environment, the proxy information that is pushed down from the ASA upon a VPN connection is not viewed in the browser until you open up a terminal and issue a scutil --proxy. This prevents the user from establishing a tunnel from outside the corporate network, and prevents AnyConnect from connecting through an undesirable or illegitimate proxy server.
In the Proxy Settings drop-down list, choose IgnoreProxy. Ignore Proxy causes the client to ignore all proxy settings. No action is taken against proxies that are downloaded from the ASA. When exposed, this tab lets the user set proxy information. Hiding this tab prevents the user from intentionally or unintentionally circumventing the tunnel. The tab lockdown is reversed on disconnect, and it is superseded by any administrator-defined policies applied to that tab.
The conditions under which this lock down occurs are the following:. The ASA configuration specifies Connections tab lockdown. The ASA configuration specifies a private-side proxy. A Windows group policy previously locked down the Connections tab overriding the no lockdown ASA group policy setting.
You can configure the ASA to allow or not allow proxy lockdown, in the group policy. To do this using ASDM, follow this procedure:. The Proxy Server Policy pane displays. Click Proxy Lockdown to display more proxy settings. Uncheck Inherit and select Yes to enable proxy lockdown and hide the Internet Explorer Connections tab for the duration of the AnyConnect session or; select No to disable proxy lockdown and expose the Internet Explorer Connections tab for the duration of the AnyConnect session.
Click Apply to save the Group Policy changes. For Windows: Find the proxy settings in the registry under:. If Client Bypass Protocol is enabled for an IP protocol and an address pool is not configured for that protocol in other words, no IP address for that protocol was assigned to client by the ASA , any IP traffic using that protocol will not be sent through the VPN tunnel.
It will be sent outside the tunnel. If Client Bypass Protocol is disabled, and an address pool is not configured for that protocol, the client drops all traffic for that IP protocol once the VPN tunnel is established. Next to Client Bypass Protocol , uncheck Inherit if this is a group policy other than the default group policy.
Click Enable to send that IP traffic in the clear. Click Apply. Beyond the static inclusions or exclusions typically used to define split tunneling, the dynamic split tunneling inclusions or exclusions address scenarios when traffic pertaining to a certain service needs to be excluded from or included into the VPN tunneling. You can configure a distinct split tunneling setting for each IP protocol. For example, you can enable dynamic split include tunneling for IPv4 such as IPv4 split include and dynamic split include domains , and you can enable dynamic split exclude tunneling for IPv6 such as IPv6 tunnel-all and dynamic split exclude domains.
Additionally, AnyConnect release 4. The limits also vary from static split tunneling to dynamic split tunneling. With dynamic split tunneling, the limit goes to characters about domain names and is only enforced via truncation on the client. Dynamic Split Exclude Tunneling —Multiple cloud-based services may be hosted on the same IP pool and may resolve to different IP addresses based on the location of the user or the load of cloud-hosted compute resources.
Administrators who only want to exclude a single such service from the VPN tunnel would have a difficult time defining such a policy using static exclusions, especially when ISP NAT, 6to4, 4to6, and other network translation schemes are also considered. With dynamic split exclude tunneling, you can dynamically provision split exclude tunneling after tunnel establishment, based on the host DNS domain name. For example, a VPN administrator could configure example. When the VPN tunnel is up and an application attempts to connect to mail.
Enhanced Dynamic Split Exclude Tunneling — When dynamic split exclude tunneling is configured with both dynamic split exclude and dynamic split include domains, traffic dynamically excluded from the VPN tunnel much match at least one dynamic split exclude domain, but no dynamic split include domains. For example, if a VPN administrator configured a dynamic split exclude domain example.
Dynamic Split Include Tunneling —With dynamic split include tunneling, you can dynamically provision split include tunneling after tunnel establishment, based on the host DNS domain name. For example, a VPN administrator could configure domain. When the VPN tunnel is up and an application attempts to connect to www.
Enhanced Dynamic Split Include Tunneling —When dynamic split include tunneling is configured with both dynamic split include and dynamic split exclude domains, traffic dynamically included into the VPN tunnel must match at least one dynamic split include domain, but no dynamic split exclude domains.
For example, if a VPN administrator configured domain. Both static and dynamic exclusions can coexist. While static split tunneling is applied when the tunnel is established, dynamic split tunneling is applied when the traffic to the domain occurs, while the tunnel is already connected. Include Specific Networks—Dynamic exclusions are only relevant if at least one IP address of the excluded host names overlaps with a split include network.
Otherwise, the traffic is already excluded from the VPN tunnel, and no dynamic exclusion is performed. Enhanced dynamic split exclude tunneling applies to "tunnel all" and "split exclude" tunneling. If both dynamic split exclude and dynamic split include domains, as well as split include tunneling, are configured, the resulting configuration is enhanced dynamic split include tunneling.
Umbrella Roaming Security protection is active when either static or dynamic split tunneling is enabled. You may have to statically include or exclude the Umbrella cloud resolvers from the VPN tunnel, unless they are reachable and can be probed by the VPN tunnel.
Dynamic inclusion or exclusion covers only IP addresses not already included or excluded. When both static and some form of dynamic tunneling is applied and a new inclusion or exclusion needs to be enforced, a collision with an already applied inclusion or exclusion may occur. When a dynamic exclusion is enforced which contains all IP addresses that are part of a DNS response matching an excluded domain name , only those addresses not already excluded are considered for exclusion.
Likewise, when a dynamic inclusion is enforced which contains all IP addresses that are part of a DNS response matching an included domain name , only those addresses not already included are considered for inclusion. Static public routes such as split-exclude and critical routes such as the secure gateway route take precedence over dynamic split include routes.
For that reason, if at least one IP address of the dynamic inclusion matches a static public route, the dynamic inclusion is not enforced. Similarly, static split-include routes take precedence over dynamic split exclude routes. For that reason, if at least one IP address of the dynamic exclusion matches a static split-include route, the dynamic exclusion is not enforced.
While the VPN tunnel is connected, you can see what is set for dynamic split tunneling in several ways:. Dynamic routes are also included in the exported statistics. Route Details tab—Shows the IPv4 and IPv6 dynamic split exclude and include routes with the host names that correspond to each excluded or included IP address.
In excess of routes, truncation occurs, and you can run either route print on Windows or netstat -rn on Linux or macOS to view all routes. With dynamic split tunneling, you can dynamically provision split exclude tunneling after tunnel establishment based on the host DNS domain name.
Dynamic split tunneling is configured by creating a custom attribute and adding it to a group policy on ASA. Define the custom attribute type in the WebVPN context with the following command:. The attribute value contains the list of domain names to exclude from the VPN tunnel and must be in comma-separated-values CSV format using the following as an example:.
Attach the previously defined custom attribute to a certain policy group with the following command, executed in the group-policy attributes context:. Enhanced domain name matching is supported when dynamic split exclude tunneling is configured with both dynamic split exclude and dynamic split include domains. Enhanced dynamic split exclude tunneling is configured by creating two custom attribute and adding it to a group policy on ASA. For example, when example.
The attribute value contains the list of domain names to exclude or not from the VPN tunnel and must be in comma-separated-values CSV format using the following as an example:. Attach the previously defined custom attributes to a certain policy group with the following command, executed in the group-policy attributes context:. With dynamic split tunneling, you can dynamically provision split include tunneling after tunnel establishment based on the host DNS domain name.
The attribute value contains the list of domain names to include into the VPN tunnel and must be in comma-separated-values CSV format using the following as an example:. A custom attribute cannot exceed characters. A list of dynamically included domains in CSV format may need to be partitioned into smaller values if exceeding the limit. Enhanced domain name matching is supported when dynamic split include tunneling is configured with both dynamic split include and dynamic split exclude domains.
Enhanced dynamic split include tunneling is configured by creating two custom attribute and adding it to a group policy on ASA. For example, when domain. The attribute value contains the list of domain names to include or not into the VPN tunnel and must be in comma-separated-values CSV format using the following as an example:. PTR queries matching any of the tunneled networks are allowed through the tunnel. To configure split DNS for split include tunneling in the group policy, do the following:.
If they do, name resolution may not function properly. For example, you can use a ping or web browser to test the split DNS solution. To use the client to check which domains are used for split DNS, follow these steps:. Those extra domains added after establishing the tunnel are the domains used for split DNS.
This process assumes that the domains pushed from the ASA do not overlap with the ones already configured on the client host. When enabled in the profile editor, AnyConnect retrieves the updated CRL for all certificates in the chain. It then verifies whether the certificate in question is among those revoked certificates which should no longer be trusted; and if found to be a certificate revoked by the Certificate Authority, it does not connect.
Refer to Local Policy Preferences for further information. When a user connects to an ASA that is configured with a server certificate, the checkbox to trust and import that certificate will still display, even if there is a problem with the trust chain Root, Intermediate, etc.
If there are any other certificate problems, that checkbox will not display. IPsec and SSL connections perform name verification on server certificates. If a Subject Alternative Name extension is present with relevant attributes, name verification is performed solely against the Subject Alternative Name.
Relevant attributes include DNS Name attributes for all certificates, and additionally include IP address attributes if the connection is being performed to an IP address. If a Subject Alternative Name extension is not present, or is present but contains no relevant attributes, name verification is performed against any Common Name attributes found in the Subject of the certificate.
If a certificate uses a wildcard for the purposes of name verification, the wildcard must be in the first left-most subdomain only, and additionally must be the last right-most character in the subdomain. Any wildcard entry not in compliance is ignored for the purposes of name verification. In response to the increase of targeted attacks against mobile users on untrusted networks, we have improved the security protections in the client to help prevent serious security breaches.
The default client behavior has been changed to provide an extra layer of defense against Man-in-the-middle attacks. When the user tries to connect to a secure gateway, and there is a certificate error due to expired, invalid date, wrong key usage, or CN mismatch , the user sees a red-colored dialog with Change Settings and Keep Me Safe buttons.
The dialogs for Linux may look different from the ones shown in this document. Clicking Keep Me Safe cancels the connection. The current connection attempt is canceled. If the user un-checks Block connections to untrusted servers , and the only issue with the certificate is that the CA is untrusted, then the next time the user attempts to connect to this secure gateway, the user will not see the Certificate Blocked Error Dialog dialog; they only see the following dialog:.
If the user checks Always trust this VPN server and import the certificate , then future connections to this secure gateway will not prompt the user to continue. Some ASA versions may require a reboot when installing new license key to ensure it is properly activated.
