This multiple xBox at one location issue is a problem with Asus (basically all) routers as well. I know this because a gaming friend of mine came to me for help that had a new Asus.
You are not going to believe the solution I gave him. It won't work for everyone because your ISP has to not be paying attention for it to work.
His internet is through a cable modem that was configured as a bridge. This modem could also be configured as a router and it has 4 Ethernet ports.
His previous router was a older Linksys E3000 which he still had left over after replacing it with the Asus.
I told him to plug both the Asus and E3000 WAN ports into the modem's Ethernet ports. Then I told him to make the SSID's different for the Asus and E3000.
After that I told him to power cycle the modem. Guess what each router got a Public IP Address!
So now when he is gaming with his brother one xBox connects to the Asus and one to the Linksys. Problem solved.
Then when he wants to transfer files or media they both connect to the same router.
Just rebooted the modem and router and my NAT is Open again.
