Hey, I'm running a linksys befsr41 rev. 4, and of course it has to be one of the routers that you have to tweak in order to get network address translation to work for the xbox 360. So my problem starts with the fact that you need to open ports 3074 udp/tcp and port 88 udp to get NAT to show up as open. Well when I boot up my xbox it likes to randomly switch between 192.168.1.100 and 192.168.1.101 and for some reason whenever I manually set this I get DNS errors. Now on my linksys settings page, I have 5 spots in which I can open ports, and I need 6 in order to cover these 3 ports for 2 different IP addresses, does anyone know how I can get that 6th port in there, or another fix possibly?
