2 XBOX One's on Pace 5268AC
Until 2 weeks ago I had 2 Xbox Ones connected to WRT54GS running Tomato 1.28 via Bridge mode from an NVG589 AT&T gateway. Everything was working fine until it wasn't. I called support and they said my router was broke and they would send me replacement asap. So 3 days no gaming. The replacement router was a Pace 5268AC. I put it in place of the NVG589 and set it to DMZ to the WRT54GS without issues. This worked for one week. On 11/13/15 my son told me he couldn't connect to his friends xbox live games and that his NAT was STRICT. I checked my xbox and it was STRICT as well.
So far I have reset both routers to factory default and put my previously working configuration back on both routers but now it doesn't work.
I tried setting up 1 xbox straight to the gateway alone = Strict NAT
I put 1 xbox in DMZPlus alone = Strict NAT
I tried a newer ASUS RT-N12 router as DMZPlus with 1 xbox = Strict NAT
I tried port forwarding 1 xbox alone on ASUS RT-N12 as DMZPlus = Moderate NAT
53 UDP & TCP
3074 UDP & TCP
3075 UDP & TCP - for COD Black Ops III
I tried port triggering 1 xbox on ASUS RT-N12 as DMZPlus = Strict NAT
I tried 1 xbox on ASUS RT-N12 as DMZPlus with UPnP enabled = Strict NAT
I've just about run out of things to try. I search the web and found all the posted solutions but most are for NVG routers. The most similar models I have found to what I have is the 2Wire and the solutions I found do not work for me.
Am I missing something. Setting up the NVG589 was easy to do with the WRT54GS as internal router.
Any suggestions you can give is greatly appreciated.
I have not called support yet but plan to this afternoon but confidence is low.
