My friend and I have been trying to play games together, but to no avail. At first, he couldn't host any games; but we fixed that. He can host games just fine now. I can't host games because I'm on my apartment complex's T1, but I've forwarded all my ports on my router anyway and I can join any game and play just fine.
The problem arises when he hosts a game, and I join. The game starts off fine, but anywhere from 30 - 2 minutes into it I ALWAYS lag out and drop. We're on Ventrilo talking to each other the entire time, so it's not a bad connection. We both can join another game hosted by someone else and play just fine as well. I've gone over his house before, hosted games there and there are no lag outs.
Any ideas?
