My friend owns a gaming center and he recently got a T1 ran into his business. There are a few problems though, the way its set up, there is a 16 port switch that is connected to a bridge that is then connected into a linux box that serves as the router. When we set up an xbox to play halo on xbconnect (www.xbconnect.com), xbconnect serves as a tunnel program for the xbox, we could not host any games, only join. We called the isp and they were supposed to allow port 8602 that is needed for the program, but still its not working. I ran netstat and it showed that 8602 was listening on both udp and tcp. He is having the same problem trying to host medal of honor servers, they can join, just not host. Someone said it may have something to do with NATd but really we are lost here, can someone shed some light to our problem, we are starting to get extremely aggrevated because it seems its more of a service problem, rather than us doing something wrong, but please someone help, thanks in advance.
