Nat Type Strict, Double NAT/UPnP unsuccessful

Namhel13 · Mar 25, 2020

Hello,

I got a new ISP last week and since then I have had a strict NAT type on my Xbox One X. First thing I did was go into my router settings(TP-Link C5 AC12000) and make sure that UPnP was enabled. Whenever UPnP is enabled I get the double Nat type detected
error. I also tried port forwarding all of ports that are listed on Xbox support page and using DMZ. Neither of which helped. When either port forwarding or DMZ is enabled I still get a strict NAT type, but the error changes to UPnP was unsuccessful.

Due to where I'm currently living I have fixed wireless internet. A wire winds down my roof from the antenna which then hooks into a PoE (I think) and that goes directly to my router. So the double NAT is a little confusing since I only use one router and
no gateway or modem. I tried all of the solutions above using both wireless and wired, and even tried using an older router that was around my house. All of which had the same exact outcome. I've spent hours going through forums and watching videos and have
yet to find a solution. The only think I can think of is that my ISP uses CGN and that is the other Nat that Xbox Live is picking up. Does anyone else have any Ideas or solutions?

:)

My networking knowledge isn't super extensive but if I understand correctly, bridging would only need to be done if there are multiple routers/modems running NAT on the same network. As I stated above I only have one router.

Hello @namhel13 I have the exact same issue as you do. I mean exactly fixed wireles due to where I live, a POE connected to the cable that comes from the satellite on top of my house, and the a ethernet cable from POE to my netgear r7000 router and i always
show a double NAT type. Ive done all the steps you had posted with forwarding ports, dmz, upnp which never says it works and i have no idea what to do been stuck here forever. Did you have any luck on find a solution to this problem? Any advice would greatly
be appreciated. Thank you.

Thank you so much for respoonding. Ok i apoligize i guess i didnt see that part in your post about the public ip. Mam that really sucks. Like i said i habe fixed wireless at 15 down 5 up and i game a ton but lately i have had so much lag and disconnects
its like why even keep trying. But then i have peiods where i have a decent ping and no lag whatsoever. What really sucks is i literally live about one mile drom people that can get fiber connection at 1000 down which i cant even imagine. I would be happy
with 40 down and like 10 up. Ive been looking into elon musk starlink internet that foes into beta testing soon and am trying to get into that. From what they say it will off fiber lije speeds but the best will be the very very low latency tou will get due
to the satellites being so close to earth which will be great. Beta testing starts in july i believe but ita hard to get picked im im s with qll the people trting ro be a parr of it. But 2021 it will offer service to most of the U.S. So that will be where
i go for sure. Us i pay 75 a month for minr right now which is crazy. 75 dollars for 15 down 5up which i never get. Its usually like 13 down 3 up. Are you still using fixed wireless.?
