Until very recently, I used VNC in a very similar environment, including the Cisco VPN.
In my case, the Cisco VPN Concentrator was not "outside" the Pix firewall, but parallel to it. So when I establish a VPN connection, I am not going through the firewall at all. Can you access other services/servers going through this same setup? Ie, when you have a VPN connection established, can you surf a web server that is also located behind the VPN concentrator & Pix firewall?
