I'm at my wits end here. I setup a second Xbox 360 for my kids (both retail) and bought both of them Xbox Live Gold accounts. It worked great for a couple of months and then out of the blue, one of them started getting NAT errors and limited Xbox Live connections. I found that if I power cycled my gateway then the one I was having problems with would work fine but the problem would follow to the first one that was working.
After doing some research, I learned that most of the time, NAT problems are due to router issues not supporting UPnP. After more research and some digging, I found that my AT&T U-Verse gateway didn't support UPnP so I bought a Linksys WRT 1200 AC wireless router that does. I put this new router into the DMZ of the AT&T gateway and used the Linksys for connection but that didn't help. I've also tried putting one console into the DMZ on the Linksys and opened ports Port 88 (UDP), Port 3074 (UDP and TCP), Port 53 (UDP and TCP) and Port 80 (TCP) for the second console but that didn't help either. I've talked to AT&T several times and Microsoft and neither of them are telling me that it shouldn't work but at the same time, they cant offer any solutions. As a last resort test, I took both consoles to a friends place with a different ISP and the consoles connected to Live just fine.
I'm at a total loss here and need some help. Has anyone else had this issue? I've googled it but I'm not finding much. I can't be the only one on the planet that has two Xbox 360s and two Xbox Live accounts.

More things I've tried:
- Put one console into the DMZ on the gateway and one on the Linksys router with the above mentioned ports.
- Enabled port triggering on the Linksys for the above ports opened
- Set both consoles and Live as priority in the Linksys
- Set static IPs, gateway and DNS in the consoles
- Other crap that I can't remember right now
