The NAT type is related to port forwarding or needing to do port forwarding. You would find out what ports need to be forwarded for which ever game you play, and create those rules in the router.

The model you listed was a powerline adapter which just relays the internet signal, it doesn't function as a router with a firewall.

@Tony I have the wa850re. When I use the connection of my normal router I get NAT-type 2. But if I use the connection of the repeater I get NAT-type 3. How can I change this?

The IP address the client device gets when connected to the extender is likely different when it is connected to the router. Our extenders will give the client device a different MAC address.

Go into the router and see what is the IP address it gets, then do port forwarding for that IP too.
