I've been trying to fix this "port forwarding" issue for some time now. My brother has a server running on his laptop and I'm trying to connect to it. But I'm still getting that darned port-forwarding message.

Well, I've tried port forwarding and opening holes in my firewall, and that's not working. Maybe it has to do with the fact that I'm using Windows XP, while he's using Windows 7..?

Anyway, I'm pretty convinced at this point that it doesn't have anything to do with my gateway, because I don't have this problem with other games that use DirectPlay.
