Are you sure that you port forwarded correctly? The Xbox One needs the ports 53, 80, 88, 500, 3074, 3544, and 4500 to be port forwarded. Port forward all of these ports and then reset your Xbox One to see if your NAT opens.

If your Router blocks the Teredo Port UDP 3544 you can´t do anything against it. XBOX one needs that you Router can use the UDP Port 3544 8you so NOT need to Port Forward or open the port).

Many Routers like Fritz Box block Teredo Port by default - So the Fritz Box gets an Firmwareupdate where you can enable NOT to block this Port.

You can try to update your Firmware of your Router and you can search how to enable the teredo Port (like I said above you don´t need to port Forward this Port)

You need to open your NAT on your router. There are 2 ways to this. Some sophisticated smart routers have a gaming preference, which will automatically open ports for you. If you do not have this option, you need to port forward the ports for xbox. You will
need to open the following ports :

Port 88 (UDP)

Port 3074 (UDP and TCP)

Port 53 (UDP and TCP)

Port 80 (TCP)

Port 500 (UDP)

Port 3544 (UDP)

Port 4500 (UDP)
