I've been trying to play Halo on the Internet using the multiplayer setting without much luck. When trying to join a game, it times out and says "Unable to join the game server". My question is what to I need to setup on my router to get this to work? Do I need to forward the client port, 2303, or do I just need to forward the server port, 2302 or both to get this to work (as well as opening Mac OS X firewall)? Do I need to enter my WAN in the IP address field? The problem could be with my DSL. They closed a bunch of ports a few weeks ago without telling me which has cause other problems. This shouldn't be as hard as it is. I thought I was a super genious with computers, now I'm beginning to doubt myself. So, if you have a router at home and run Halo MP and you've got it to work, I would appreciate info on how you've got it setup. Thanks a ton.
