Xbox Strict NAT - UPnP Unsuccessful

Hi - As from the subject line above you can probably guess that I'm having some networking issues with my Xbox stuck on a Strict NAT & UPnP being unsuccessful. 

My current network is as follows --> ISP Router [Hub 4 in Modem Mode] --> Netgear RAX70 Router --> Connected Devices [ Phone | Xbox | Etc ]

I'm sure I've tried every solution I can think of and found scouring the internet for the same issue

- Hard Reset on both ISP Router | 3rd Party Router & Xbox 

- Port Forwarding - Tried with both UPnP enabled and disabled

- DMZ set up - Tried with both UPnP enabled and disabled

- Changed ethernet cables incase this is an issue 

- Turned UPnP off and reset & Turned back on and Reset. 

unfortunately none of the above was able to resolve my issue. I resorted to calling up VM this morning however the adviser on the other side was unable to offer any solutions and advised to keep my VMHub 4 in router mode whilst connected to my 3rd party router [ Pretty sure this could cause further issues!?!?] and then after half hour of back and forth was advised that they could instead transfer me to a specialized team however there is a transfer costs of £9.99?

Does anyone else have any insight or able to throw any suggestions my way I'd be greatly appreciative!

DMZ without Port Forwarding or UPnP enabled should of worked maybe you put in the wrong LAN IP for your Xbox?

Their might be a NAT setting you need to change called NAT Filtering

I'm not sure - I tried all of the combinations I could think of but to no avail.

Been busy this morning messing around with it and decided to do a full reset and connect each ethernet device 1 by 1 and have came to the conclusion that one of the connected devices I have [ Kantar | BarbTvPanel box ] is causing the NAT issue and somehow effecting UPnP - from my knowledge the equipment that they set up acts as a medium to collect telemetry data via sound from whatever I'm watching & broadcasts this one way or another to their systems
