I remember having my xbox using the Gaming (Port Forwarding) rule. Thats when I had a single xbox. Having to, you can only port forward the one port for XBL to a single console. When my buddy was trying to get his going, we couldn't figure out why the 2nd xbox wouldn't sign in correctly while the other one had the port forwarded to it. We figured out that we had to remove the gaming rule for XBL and use Gamefuel to set up multiple consoles to the XBL port. I supposed you could use gaming if you only had one console and it would work. I think it will work with Gamefuel on as well if it's set up...Let us know how you have it or what you find that works well for a single xbox.
