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.)
 
In order to port forward the same ports you need two public ips and two routers. the service might have several ports available to let you do more than one per ip. You would have to set the rules yourself.

Someone outside your network sees your traffic as your public ip so when they try to communicate to a specific port the router forwards it to an internal address.

upnp and "dmz host" are lazy/insecure way of port forwarding without manually entering the rule. the concept is the same. It's insecure because it's letting inbound connections on any port.
