Double NAT detected with BGW320 and RT-AX86U Pro

[ShrimpySkimp78]

I have my BGW320 modem set in IP Passthrough with all of the firewall settings turned off and connected to my RT-AX86U Pro but I keep seeing double nat detected on my Xbox series X. Am I missing a config or something on my Asus Router to fix this? I'm not sure what else I can try to get rid of the double nat, any help is appreciated!

What are the first two octets of the "WAN IP" shown on the router's Network Map page?

Is your Xbox being routed through a VPN? If so that will be the reason.

You nailed it, I turned off the VPN and it was gone. Thanks a ton I've been searching for this answer for over a year now! LOL

Give this a try - it seems to be a common this with how ATT has implemented the BFW320...
