Airport Express,, And Port Forwarding



I've got an Airport express and I can't seem to log on to I get an error: Unable to connect to, regardless of what realm or game I'm trying to play. I've gotten Halo and JK2 working, which is odd...

I've been trying to set up port forwarding to open the ports. To do that though I need to distribute IP addresses. Once I do that, my internet connection dies.

Any suggestions? Thanks!
