It's been a little bit, I suspect the issue was getting my modem and router to allow that type of traffic. It wasn't the firewall. I remember spending a lot of time trying to get port forwarding set up so these fucking things would talk to each other the way I wanted and that's when I hit the "you can't do this with your set up try something else" message in the last guide I looked at.

Ah yeah, that can certainly be a bitch. I don't remember what server I was trying to get port forwarded and my God awful ISP's hardware all but prevents you from doing things the conventional way.
