RV34x: Install Cisco AnyConnect Secure Mobility Client on a Windows Computer - Cisco - The guarantee of Cisco Security
Greetings, we just deployed anyconnect 4. Surf the internet securely with good connectivity. With Cisco VPN, you can browse the internet anonymously. The tool reconnects automatically after the connection drops. Save Accept All. A client license enables the VPN functionality and are sold in packs of 25 from partners like CDW or through your company's device procurement. Open a web browser and navigate to the Cisco Software Downloads webpage.
In the search bar, start typing 'Anyconnect' and the options will appear. The images in this article are for AnyConnect v4. Select option 2. You will need to know your Cisco ID the one you use to log into Cisco. If the AnyConnect VPN 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 the 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 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, the 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:. When captive portal is detected but network access is restricted by AnyConnect , the AnyConnect browser is automatically launched, with the following message displayed to prompt the user to remediate:.
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. This situation can occur when a user is on an internal network, and connects through a firewall to connect to the Secure Firewall 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:. Exit and restart AnyConnect. 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 preferences 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 are 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 — 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 Secure Firewall ASA require AnyConnect configuration to support clientless portal access through a proxy server after establishing the AnyConnect session. AnyConnect uses a proxy auto-configuration PAC file to modify the client-side proxy settings to let this occur.
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.
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. In a macOS environment, the proxy information that is pushed down from the Secure Firewall 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. 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:. 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 user and system proxy settings in the registry under:. 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. Split tunneling is configured in a Network Client Access group policy. Create a tunnel-from-any-source custom attribute and when set to true , AnyConnect permits packets with any source addresses in split-include or split-exclude tunnel mode, allowing network access inside the VM instance or Docker container.
The network used by the VM instance or Docker container must be excluded from the tunnel initially. 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 cannot configure a distinct split tunneling setting for each IP protocol. For example, if you enable dynamic split include tunneling for IPv4 such as IPv4 split include and dynamic split include domains , you cannot enable dynamic split exclude tunneling for IPv6 such as IPv6 tunnel-all and dynamic split exclude domains.
