I agree with lnorris, it's not a great idea to keep your computer on the DMZ permenately. Your computer is unprotected aginst hackers. I often set my computer on the DMZ to host games of this sort, and after I'm done, I remove myself from the DMZ. (heh, I know that 98% of the people out there are reading this and saying " what the heck are these guys talking about???) Anyways.....PM me if anyone has a specific question....I'd love to try to help.
