Out dated the new 660 is out now i dont have an xbox 360 any more so if it doesnt help sorry stop sending messages i cant help you becuz xbox live bann me i now play on pc . pc games are the real way for playing a games noobs play on console.Here is how you do it. Open up the modem’s interface by going to 192.168.2.1 type the default modem password “1234″ and go to firewall. Go to default policy and set everything to permit. Save the settings. From the main menu, click “UPnP” and check all the check boxes. Save the settings. After doing this, if you run a network test on the 360, it should show the NAT is now open. Please let me know if this helps. it does not work for everyone but give it a try if not call embarq i do not have an xboz 360 account any more
