This is an older topic and shouldn't be questioned but I cannot fix the nat type on my xbox. I have done everything possible. I ain't a techy person... At all... mostly no clue what I am doing. But I did everything I could find on how to fix this problem. I have it wired to my Gateway Router which is a Arris DG1670. But in all seriousness. I have tried a lot. Wireless, Port Forwarding, Static IPs, DMZ, nothing works at all. Maybe it is the router, me, ethernet cable, idk. It is striaght up plugged into it. My router doesnt notice the xbox one when it is plugged in but notices it when wireless but it still stayed strict with portforwarding. Idk... I am a fool with this stuff.... pls help
I have been successful with putting my Xbox on DMZ with this router. At first I had trouble with the DMZ until I read somewhere that you have to make sure that you enable your firewall. So you go to the firewall tab and enable firewall with The DMZ settings and it should work. Remember though you can't have any other settings such as port forwarding or it may not work so clear out any other settings you may have tried.
