I am playing a game called supreme commander. Games are started by players meeting in a "lobby" and then the game launches. The problem is, I can't connect to most of the people. The game doesn't say why, it just says "nil" which means it can't connect.
I have what I think are all the right ports open. I am not seeing any dropped packets in the logwatch. How can I figure out why the game is having a hard time connecting to people? It must be a firewall problem, because if I connect directly to my modem (bypassing the firewall), I have no problems.
