You could put your Xbox in the DMZ of the T-Mobile LTE device. This places your Xbox outside of the LTE's firewall. The 5 G silver cylindrical T-Mobile device doesn't have this ability yet.

The DMZ functionality on the LTE gateway doesn't do anything. T-Mobile is 464XLAT for ipv4 and filtered unsolicited inbound for ipv6. That means you effectively always have double nat no matter what.

This is really getting on my nerves tmobil should send an update or something i cant do anything. I really need to get this doubble nat thing resold. Any luch out there? Any one complaining to tmobile?

Can some one please enlighten me on this double nat type bs please tell me they will fix this soon on the new 5g arch modem 

Not sure which xbox version you have, but on Xbox One X that I own, I go into the network settings and click test NAT. Repeat the process until it detects things correctly. I did not try party chat with mine, but I did hear others in game lobbies.

Double NAT usually means you have a router connected to another router, and they are not forwarding ports. So, in your case, you are connected directly to a single router, so you are not double natted. You're just single natted, which can still cause issues.

I have the same issue on my Xbox Series X. I never used to have the issue. I only have the T-mobile white internet box. No router or anything else connected. What am I doing wrong? 

Have you guys had any luck with this?  I'm having the same issue - its saying Upnp was not successful.  Any ideas would be great!

Unfortunately, the fix is not just something as simple as a firmware update to their modem/router.

The core problem lies in their network topology on the other side of the modems.  Basically, an infrastructure design issue that needs to be reworked first.  They have large banks of v4 addresses, but for whatever reasons they will not assign those to us on a 1-1 basis like they do with the likes of Spectrum or ATT... instead they are used more like a VPN, potentially sharing one address with multiple clients (like a CGNAT setup).

As mentioned earlier: XLAT464. This is what they implemented to deal with mixed IPv4/v6 through the IPv6 portions of their network.  As mentioned in the RFC on this like a decade ago, this core design breaks unsolicited inbound traffic that would require port forwarding to work.

There are some potential work arounds they could put in place, but it would require considerable resources and partial redesign of their networking strategies to make it work how we would need it.

Some have mitigated issues with their own VPN's, but YMMV... it would need to properly support P2P traffic, and in the case of game consoles would need to be running on a router as well.

I am a network engineer and I am not dealing with this double NAT baby back BS.
I’ll be back once they get their act together, maybe.

It's BS needs to advertise as a hotspot not home internet we don't get proper access to hardware nor a public IP, it's definitely not "home internet". I hope they realize there is a great number of people working from home and online gaming from home too, if I have to pay for extra services (VPN/NGROK) to get basic functionality working I may as well stay with cox and pay for simplicity, a public IP and somewhat decent access to the hardware. speeds can be at time better than Cox but I don't just do internet browsing and they are not stable by any means.

I would use this only if you don't work from home, do not game online and or if you have no other option, lol.

Was going to do some xbox gaming this holiday, guess whos double NAT’ed at the ISP level… 
What F’ing a joke this was, it was a good 2 days I guess.

I guess cox is till going to get my $.

I have VPN and I can get my xbox online but that kills my speed so.. May as well go back to Cox for now,
I hate cox but this is just worse service at better prices at best. At least until they give us access to basic hardware settings with a public IP that IS NOT DOUBLE FREAKING NAT'ed.

 

What firmware are you running on your can?  I have 1609 and have open NAT with my xbox.
