i had the same problem on my ATT dsl modem, if you have the motorola modem and not the 2wire routers, then log into your modem at
http://192.168.1.254, click go to local network at the top, click on nat/gaming on the side, click on gaming on the side then in the list select xbox live games at the bottom and click enable, restart the modem,
and you'll have a open NAT
Did this solve your problem?
Sorry this didn't help.
