Applies to all Barracuda SSL VPNs.



The SSL VPN Agent will only launch at login if there is a feature or resource commanding it to do so, there are three things that can cause this to occur.


  1. The Profile that the user is using when logging into the SSL VPN is set to launch the Agent on login. This can be checked by going to Resources > Profiles edit the Profile that the user is using. The forth option under the Agent Configuration section is Start automatically on login. If this is enabled it will cause the SSL VPN Agent to start whenever a user using this Profile logs in. This functionality can be disabled by disabling the Start automatically on login option.

  2. A Resource that requires the Agent has been set to Auto Start. All Resources have the option to automatically start when a user logs into the SSL VPN, if this is enabled on a resource that requires the use of the SSL VPN Agent then this will start in order to launch the resource, the resources that require the Agent are:

    All Application types
    Tunneled Web Forwards
    SSL Tunnels

    To see if a resource is set to Auto Start, login as ssladmin and edit the resource types listed above, the Auto Start option can be found in the Details section of the options. To disable the functionality simply disable the Auto Start option on any resources that have it enabled.

  3. Network Access Control (NAC) is enabled on the SSL VPN unit. When NAC is enabled the SSL VPN Agent must be launched when a user logs in so that it can check the system meets the NAC requirements. To check if NAC is enabled log in as ssladmin and go to Access Control > NAC under the OptionsStart Access Control option. If this is set to Yes then NAC is enabled. To disable NAC set the Start Access Control Option to No.
