Multi-Xbox Home - Random Nat changes and Poor Connectivity

First thing First, The questionnaire:

What Country/State/Province do you live in?: United States of America

Modem brand & model number: Motorola SBG-6580 in Bridge Mode

Router brand & model number: T-Mobile Branded Asus RT-68U using the latest T-Mobile provided firmware and a Netgear Wndr-3700v3, as well as a D-link dgl-4300. Both Netgear and Dlink have the latest firmware and are configured
as Access points. Both are Wired via ethernet to a wired Moca Bridge (also netgear).

How many Xbox 360 and Xbox One consoles are connected to this router?: 3 XBOX Ones (2 on the latest Preview Build). 1 Xbox 360.

Wired or Wireless (for each console): Wired

Things you have tried: Updating firmware, factory resetting equipment and resetting up network, removing routers from the equation. Disabling / enabling firewalls, port forwarding, DMZ.

Is UPnP Enabled? Yes/No/Unknown: Yes

Do you have a NAT error? If so, what is your NAT type?:
Nat type changes, goes from open to moderate to strict. This is only affecting the 2 xbox ones on the preview build.

Any Error Codes you encounter: none

Who is your ISP? (Internet Service Provider): Time Warner Cable

What is going on:

So, recently we started getting a lot of connectivity issues between the 2 xbox ones on the Preview program. From what I can see the XBOX 1 on the regular OS does not appear to have a problem. The other two keep swapping
Nat modes with the XBOX wired to the router direct getting priority. This started happening approximately 2 months ago and as it has never been an issue prior I do not believe this to be a networking issue (although I could be wrong).

None of my hardware has had any firmware updates in several months. This is only affecting the 2 xbox's we have on the preview program. I figured I would reach out here and see what y'all say because this is kicking
my butt.

Respectfully,

Port forwarding question

Well, the Open NAT lasted about half an hour. Started OK, then I got dumped out whilst loading a new game - NAT type reverted to moderate, and I can no longer connect to an online game. Still a static IP address and none of the other settings have been changed.

I'm reaching the end of my tether here, any suggestions? How do I disable UPnP? I have a home hub 3 too.

 

Windows 10 - Error "0x87DD0003" when login

Hi Brad,

For information, I reinstalled Windows with the 1809 version but no change.

I tested with custom DNS on my Windows. (My Xbox is ok. NAT is open and connectivity is ok).

Server connectivity is always "Blocked".

My configuration:

Hey there TheVagueOne!

Sorry to hear about the connection issues! Since you are participating in the Preview Program, I recommend making a post in the Xbox One Preview Forum. This way the proper folks
can address the issue. If you run into any issues accessing the link, be sure to let us know. Thanks in advance!
