3 xbox 360s in one house but one is nat restricted?

We have three Xbox 360s in one house. One only connects to the local network and the other two are connect the Xbox live. The local Xbox 360 and the other Xbox 360 (which is connect to Xbox live) are a standard xbox 360 and mine is a Xbox 360 slim.

Now for some reason the Xbox 360 slim has NAT restriction and we cant figure out why. We have opened ports 53, 80, 1863, 3074 and enabled Upnp and still nothing works. The only other thing i can think of is port forwarding to the Xbox 360 slims ip but we want to stay away form that if possible.

You shouldn't use port forwarding if you have more than one xbox. You should only use UPnP.

Most routers will not allow you to port forward the same port to more than one device.

Also not all routers will allow multiple xboxes to be connected at the same time with an open NAT.

Port forwarding conflicts with UPnP as does DMZ. Make sure to have Port forwards and the DMZ off if using UPnP
