Hmmm... Well, the nuts and bolts of it are that the faker will connect to whatever hostname or IP address is specified in the VGL_CLIENT environment variable. When you connect with vglconnect -s, an SSH tunnel is established for the VGL Transport, and a script (vgllogin) is run on the server. vgllogin sets the VGL_CLIENT environment variable to localhost and the VGL_PORT environment variable to the appropriate port for the server's end of the tunnel. When you don't use vglconnect -s, then VGL_CLIENT is set based on the SSH_CLIENT environment variable. So the first thing I'd check is whether SSH_CLIENT is being set when you SSH into the server.
