For the life of me I cannot figure out how to make this work. I was running TightVNC from my office PC to access my Tiger machine running Vine Server, and everything was peachy-keen. Now, however, I can't access my Leopard machine from anywhere except within my home network (i.e., typing "http://192.168.2.5" from TightVNC on home PC brings up home Leopard machine just fine). I have screen sharing turned on, password set, but no dice accessing it from outside my network (router is set up to keep www.dyndns.org updated with current IP, and is set to forward incoming traffic on VPN ports to Leopard machine's IP address). Even Vine Server no longer works. What's the deal here? Help please!
