When it comes to consoles, you are better off using DMZ...just put the IP address for the xbox360 into the DMZ list, and it will have every port forwarded, even ports only used by games that don't exist yet. If it were a PC, then DMZ would be very dangerous...but consoles don't need so much security so firewalls do more harm than good...not that they do any good at all in that situation.
