Solution #00003726

Scope:
This solution applies to Barracuda SSL VPNs, all firmware versions.

Answer:
A profile provides a means for an administrative user to alter the general working environment of the system. Settings in a profile can alter the timeouts of a user session, change the default view for resources (icons or lists) and also affect agent timeouts and proxy settings. Users can select different profiles upon login, or administrators can manage default environment settings for users.

To create a profile, navigate to Resources > Profiles. Provide a Name and select one or more Policies to associate. Click the Add button. To edit the profile, click the notepad icon next to the name of the profile you just created, located under the Profiles. A new window will pop-up with all of the available configuration options.

Below is a description of the profile configuration variables:

Agent Configuration
  • Keep-Alive interval (seconds): The interval between keep-alive requests.
  • Shutdown interval (seconds): Interval in seconds to wait for before exiting the client after receiving a shutdown request
  • Registration sync. timeout (seconds): Registration timeout in seconds
  • Start automatically on logon: Start the SSL VPN Agent automatically upon logon.
  • Browser command: Command to launch browser, leave blank for automatic.
  • Web forwarding inactivity timeout (seconds): Interval in seconds to wait before offering to close a web forward tunnel, a value of 0 meant no timeout.
  • Debug level: Set debug level. Trace gives most output, Fatal gives the least.
  • Clear cache directory on exit: When enabled, the Agent will be removed from the clients computer upon shutdown. When disabled, the Agent's program files will be left inside a hidden directory, enabling a faster start up time on next use.

  • Remote tunnels require confirmation: Enable this option to require that the user accept remote tunnel connections.
  • Localhost address: The address to use when the server needs to connect to the loopback address on the client. For example, this may be set to 127.0.0.2 as a work-around for connection problems when using the RDP extension on Windows XP SP1.
