Call the the Emperor's New Clothes Firewall Buster: Although the purists will scoff you can always "cascade" VNC sessions, which I do all the time. VNC into a machine which is multihomed, or is in some sort of outside-the-firewall DMZ. Then, fire up a VNC viewer --on that machine-- and connect on port 5800/5900 (the standard ports) to any other machine on your LAN behind the firewall. Last I checked, firewalls are too dumb to block content - they're only good for blocking packets.
Disadvantage? It is slower and choppier than a direct connection. Advantage? It works immediately. 100% of the time.
