Need help changing your NAT from Strict to Open? Check out the article above!

I currently have opened ports on my Arris NVG589 gateway for an Open NAT Type for my Xbox One console.  Now, I am adding a second console (second user in the household), but get a Strict NAT Type for it.  How do I get an Open NAT Type for the second console?  Thanks for the help.

Hi @DBRhodes279,

Moved your question to our XBOX thread. Hope it helps!

Not working for me. 

My understanding is that u can not get them setup properly because the modem dies not support upnp.i have the same problem and have a nighthawk hooked up off the nvg 589 my nat is strict however and am looking for a solution to it.

My nat type is stuck on strict or if im

lucky, moderate. Anyone know how to

open the nat type for online gaming?? Never had this problem until I switched to At&T. Thanks!!

Thought I would share...

For those that are experiencing issues with multiple Xbox One's.  I solved it by getting a $19 router (Inexpensive UPnP Router).  Use the supplied cable, connect the new routers WAN port to any of the 1 of the 4 CAT 5 ports on the Uverse router.  Set the new router as the DMZ host on the UVerse routers firewall settings.  Restart everything (consoles, new and old router).  Go into your network settings on the consoles, find your new router (you could have renamed it and given new login credentials which are recommended) and let it go.  The XBox will automatically detect and configure itself via UPnP.  I have one console physically connected to the new router and another in the house connected over WiFi to the NEW router.  Both with OPEN NAT's.

(was having issues playing Conan Exiles with the nephew at the same time - this fixed it - game and voice chat.  Note we do both have our own XBox Live accounts!)

The UVerse router we have is the Pace 5268AC.

My son just got a new iPhone and we’re trying to connect to his new hotspot but it will not connect. Please help!

I know this is an older thread, but I got my two systems to both work with open NAT. The ATT gateway supports both 2.4 and 5 ghz connections. I logged into the gateway and changed the name of the 5ghz network. I then had my xbox connect to the 2.4 and my daughter's to the 5ghz. Both have an open NAT, and have worked flawlessly. 

how about PS 4?  How do I open my Nat type from strict (3) to a moderate (2) or open (1)?

Seems it is impossible to open nat for more than one Xbox even if one is direct wired and the other is wifi. It makes no sense. Att is built on gaming yet cannot fix this simple issue. If a customer wants to open nat and subject their computers to hacks att should fully allow it. This is the error when attempting to open 2. May have to create a static ip for the 2nd Xbox or just switch back to Cox who is more expensive but will let us game on Xbox properly 🤷‍♂️ 

Xbox one S live conflicts with Xbl live wired which is currently in use on XBOXONE.

Xbox one S live and Xbl live wired use the same resources and cannot both be hosted at the same time. To use Xbox one S live, you must first remove Xbl live wired from the application list of XBOXONE. Alternatively, you can install the applications on one computer and add both application profiles to the application list for that computer.

thats great that it tells to turn on upnp but the worlds crappiest router att has me handcuffed to doesnt support upnp.

I know this is an old thread, but you can now use "alternate port selection" on the Xbox one and xbox series consoles to achieve open NAT across 2+ xbox systems without UPnP. It's under "advanced settings" in the network menu on xbox. Select a different port there, then make a custom rule on your router for that xbox where you forward the alternate port on top and udp. 

For example, I have one xbox named "XBSX1" that has the Alternate Port of 54255 in xbox settings. I find that device by name in the router settings (you could also use a static up) and made a custom rule that forwards 54255 on UDP and TCP. The other xbox, named "XBSX2", has the standard port forwarded by selecting "xbox" under profiles. That is port 3074. Doing this enabled open NAT on both consoles simultaneously. 

Thank you! I'll keep that in mind if we have problems again, but so far so good.
