XBox - NAT Strict no matter what

MikeAdamsNA · May 27, 2021

I am really struggling to figure this out. A couple days ago I could not play multiplayer online games (Xbox One). I found out my NAT type changed to strict. Nothing changed on my network/router, as it’s worked perfectly for over a year. uPnP was enabled. I am using an Ethernet cable directly to the main router. It’s a Netgear Orbi RBR50.

I can see my Orbi forwarding the ports correctly on the uPnP screen on my router.

My ATT modem is not broadcasting, and is acting as a modem only, not a router (bridge mode).

I have a Netgear Orbi RBR50 router

I tried assigning a static IP address to the Xbox and assigning it to the DMZ on the router. No luck. Even with uPnP disabled. I can connect to the internet just fine, but with NAT strict.

I tried a different router with uPnP enabled. Still strict NAT. I tried to run an Ethernet cable directly from my ATT modem to the Xbox (no router at all involved). I had internet but still Strict NAT.

I have spoken with Microsoft (a joke), and ATT about this. They are all saying it’s my Netgear router, but I have taken that out of the equation.

Also, I have another Xbox One (the two are never on at the same time), and it has an open NAT. So it’s only my main Xbox One that is getting a strict NAT.

I don’t get why one Xbox has no issues and one is strict NAT. Also, since nothing changed, I don’t know why this all of a sudden happened.

Any help would be greatly appreciated! Thanks.

I have gone through all the suggested settings you listed to troubleshoot the NAT errors. None of them worked (as explained in my original post). I reset my Xbox to factory default, that did not work either. Now I do not have any of my games, and am still having the same issue.

Hey there Trea81.

Super sorry to hear about NAT type troubles with your Xbox One X. Can you share the make and model of your modem as well? Also, if you connect via wire to your router do you see any difference with your NAT type? Curious if your modem might be causing issues.

It has nothing to do with the firmware.

I solved the issue myself. It was caused by a conflict in port forwarding. I had mistakenly opened all ports for another device and because of that, the ports requested by xbox were not able to be opened even though it was in the DMZ. The device wasn't being
used but the ports were held open by the router.

Once I deleted that port forwarding command it fixed everything. I wanted to leave this here for anyone else who may have the same issue... It isn't because u have this router, there is nothing wrong with it.

Also that port forward command was entered fairly recently before I got the Xbox so I didn't pick up on it.

Thanks for posting back! Just a heads up, the Xbox Forums team works Monday - Friday, so any bump made over the weekend (or later on Friday) won't be caught till the following Monday.

After a bit of research, this seems to be a common problem that has popped up for that router, specifically with a firmware update for that router. A fix we have seen is rolling back the firmware update on your router, however we're unable to offer specific
steps to do that and reaching out to the manufacturer directly will be the best step for that.

You may have already tried this, but my first suggestion is to fully power off your Xbox One console along with removing power from your router & modem, and make sure that the first console that connects is the Xbox One. This will
make sure the router is prioritizing that Xbox One console. If the issues continue to occur, that may indicate the firmware may need to be rolled back to a more stable update.

Please keep us posted!
