Xbox 360 open NAT problem

  Wanted to see if someone could help me out. I have an AT&T Uverse router 5268acfxn which I'm having problems connect two xbox 360's to. I have n Xbox One and a 360 connect and working together same network. I can play on both systems at the same time (one person on the 360 and another on the One) playing 360 backward compatable games with no problems. But now when I try to connect a second Xbox 360's to the same network, I have a problem. The Xbox 360 that would connect with the  Xbox One and had open NAT, now has been set back to moderate. So my question is, can two 360's connect together using the 5268? If so what do I need to do in order to get both 360's to play nice with each other. Any and all suggestions and help would be appreciated.

 

Thank you for your time

The short response is to "eliminate the double NAT". 

 

Most service provider's don't accomadate for this option.  The Gateways don't support disableing DHCP, being placed in bridge mode, or providing the DMZ with the ability to assign a public ip. 

 

the solution that should be provided, and may be in the new Pace router, is one public ip for their network and one assigned to your WAN ip of your own router.

 

i solved this issue by using AT&T for cable/dvr and another company for just internet,

There are only two ways got get two XBOXen to play online behind a NAT router/gateway (and no, this is not what double-NAT means).

 

1) Use UPnP.  Since the AT&T Gateways do not support UPnP, that means getting your own router that does and placing it between your two XBOXen and the Gateway.  See see the solution in this thread for a little more detail (if you just hook it up without configuration, then you will have double-NAT, which isn't the end of the world).

 

2) Obtain multiple public static addresses (for a fee) from AT&T.  Then you can assign each XBOX a separate IP address, which also works around the NAT issue.
