Visibility
The Barracuda Server Agent is not something a user will actually see or select to use; it is actually a
background process that takes over whenever a connection needs to go out from the appliance to a
remote system.
If the administrator has routes configured and a Server Agent installed the system will take advantage
of this and proxy the traffic through the Server Agent. A user will be unaware that a Server Agent is
proxying his or her traffic. When no Server Agent is installed, the Barracuda SSL VPN will continue
to make direct connections to its target host.
The Server Agent is strictly an administrator feature to help reassurance of security; its activation
affects all resources.
