lan hosting help - behind same router we have an apple airport router that we're both connected to. i opened port 4000 and 6112 to my computer. then my roommate tries to join my game using my internal or external IP and it just stalls. if he puts a bad IP address it errors immediately, so clearly something different is happening. he can telnet to my computer, port 4000, and it connects no problem. what do we need to do to diagnose the problem, or fix it? is the problem that he needs 4000 forwarded to his computer also? (for warcraft 3 hosting we had to change his computer to host on 6113 for everything to work nicely, so we could have different ports forwarded to our computers. diablo 2 can't do that i guess). please advise.
