I have 2 PS4s in the house and but one of them is getting a NAT type 2 and the other is getting a NAT type 3. Why can't I get the second one to NAT type 2? I have tried opening all the ports, UPnP is enabled and all that. I'm really doubting its the router causing the problem and maybe the hardware is messed up or the settings? Any ideas? (both are using wireless, on the same floor and on the same network.)
