I am at my wits end! We have three XBox consoles in my home and all three keep getting a Double NAT or Strict NAT condition. I have turned on UPnp and IPV6 to no avail. I have a Motorola MB8600 modem that the documentation says is already a bridge modem, so I am not sure what else I can do. We are regularly getting kicked from multiplayer games. My current FW is 3.2.10.11Any ideas other than port forwarding or DMZ, which I am not too fond of doing.

So since the new FW was updated last night I am very happy to report that everything was stable last night and been going strong since. Although I am still getting double NAT / Strict NAT, the disconnects every 20 minutes seems to have been solved.I will work on fixes for the NAT issues but the disconnects that were driving me nuts has gone away.

I would review this:https://community.netgear.com/t5/Orbi-AX/RBR850-Double-NAT-Type-error-after-2-days/td-p/1872308/jump-to/first-unread-message Has a factory reset and setup from scratch been performed since last update?

No, haven't done a factory reset yet. We just upgraded to Cox GigaBlast, replaced my old Arris Surfboard with the new Motorola, and replace my old Orbi system with this new RBR850. Several problems so far but this is the one it the first on the list.

Power ON all three game consoles. When they are ready, hold the front power buttons until they turn OFF. Leave them off. Then I would power OFF the modem for 30 seconds then back ON. WHile this is happening, press the reset button in back of the RBR for 15 seconds then release. Walk thru the setup wizard and complete the setup. Reset the RBS as well. Be sure to check CTS and RTS values. If you see 64, change both radios to 2347. Under Advanced Tab/Advanced Settings/Wireless Settings Power ON one xbox at a time and check NAT status on the dashboard networking settings. Are the game consoles wired or wireless?

One is wired to Orbi routerOne is wired to Orbi satelliteOne is on WiFi.All three giving the same condition.When I have run the tracert I am seeing the double NAT addresses but cannot explain why. Goes straight from wall --> modem --> Orbi.I will do the steps above as suggested and post the results.After I have factory reset, are there any other settings besides the info above, that I should be looking at? Everything I have researched says to use port forwarding or DMZ and I really would rather not. I have also read info saying UPnP and/or IPv6 should solve it, but neither worked.I am a firm believer in Orbi since I am a long time user but this $600 unit is giving me fits.

How do you know it is a double NAT issue, because you are kicked off from the game?

This firmware has know problem of disconnecting from many games. The easiest way temporary is turn on your cable modem routing (rather than bridge mode), and put Obri AX into AP mode.

  No, double NAT issue is mostly if your ISP modem has a built in router while having the RBR connected. Having two routers online causes this. This issue is mostly the FW on Orbi not working right when having two or more game consoles online at the same time. I submiited a bug report already on this. ALso NAT Filter feature is working. IF set to OPEN it should help two or more game consoles attain OPEN NAT all at the same time. This feature is not working currently on Orbi AX. It works on Orbi AC.
  
  SO far I have not seen any disconnection issues after v10.11 was loaded and back in router mode. I also don't have a built in router and wifi in my modem. CM1100 is a stand alone modem.

    I know what I am talking about. Been working for CSCO for 6 years in the past, I know what I am talking about. I understand what double NAT problem is. But what you are experiencing is not from double NAT. It is a bug with their current firmware which causes Orbi AX router fequently disconnet from the game servers. Put Orbi AX into AP mode will fixed the problem at this momnent. Even you connect Orbi AX as AP to another router then connect to a cable modem as gateway router. In that case, it is still double NAT, but the problem will disappear.
    
    If you still believe this is a double NAT problem, I will not give you more comments. Sorry...
