Barracuda SSL VPN Agent Configuration
• Keep-Alive interval: Because the Agent does not have a permanent connection to the
Barracuda SSL VPN as HTTP is stateless, a heartbeat is required to inform the Barracuda
SSL VPN that it is alive. If the appliance fails to receive this heartbeat then all open
connections are closed.
• Shutdown interval: When the SSL VPN Agent is being shut down either by logging off or
clicking the shutdown button a message is sent to the Agent to shutdown. If the appliance
does not receive a de-registration request from the Agent within this configured interval then
the appliance takes it upon itself to clean up any unnecessary connections tunnels, objects etc.
• Registration sync timeout: When the Agent is launched, the Agent applet downloads and
tries to start the Agent. The applet then waits for the Agent to connect to the appliance and
send registration request. If this is not received within this allotted time then the applet is
informed and an error is raised.

• Start automatically on logon: Start the Agent automatically whenever a user logs in.
• Browser command: Command to launch browser, leave blank for automatic.
• Web forward inactivity timeout: If a Web forward has been inactive for the given duration
close the connection.
• Debug level: Set debug level. Trace gives most output, Fatal gives the least.
• Clear cache directory on exit: Enabling removes the Agent from the client’s computer on
shutdown. Disabling leaves the Agent files will be left inside a hidden directory enabling a
faster start up time on next use.
• Display information popups: Enabling this shows messages when the Agent is performing
an actions in a popup. Disabling this removes these popups and lets the Agent to operate
silently.
• Cache directory: The location for storing downloaded applications and other resources. This
directory is maintained within the users’ home directory.
• Remote tunnels require confirmation: Enabling will force the user to accept any remote
tunnel connections. Disabling will automatically create connections.
• No session timeout if active: This prevents the user session from timing out if the Agent is
running regardless of whether the Agent has any open tunnels.
• Localhost address: The address to use when the appliance 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.
