It used to be true that if you had a Vista Certfiied or Compatible router, UPnP should work properly for at least one XBOX. I presume this carries over to the new
Windows 7 HCL. Without getting into the nitty grity of NAT, PAT, and port forwarding, you want to enable UPnP on your router. That should be enough.
