What the panda are you talking about? Hahaha, this loser things forwarding ports is dangerous. Just like those cigarettes that think giving out your IP is dangerous. Worst they could do is get an, oh... lets say 100 mile radius of where you live.
All games need forwarding if you want to host. Unless the router already has it ported or you don't have a router.
Gfys.Seriously. I could find out more than I could with an IP by tracking you by adding you on AIM, which is "heedicalking", and using a simple command in the command prompt.
