PS4 can't change nat type to open, nothing works

[Alexikik]

Hello, I have a PS4 pro with a moderate nat type in games and a type 2 in the network settings. I can't seem to change the nat type to open and everything I tries, fails... I hope you guys have some suggestions I haven't tried yet

I have tried the following:
- Tried using UPnP
- Tried setting the PS4 to DMZ (With and without static IP)
- Tried portforwarding (With and without static IP)
- Tried changing the static IP and tried the above things with that new IP.

I'm "open" for any suggestions

PS. My router is conected to the lan socket in the wall, and my PS4 is conected to that router via a lan cable. In another room, my roomie has a switch with his PS4 connected, and he has a open nat type... (Same internet provider).

I am not exactly sure what is moderate NAT or type 2 but every router is pretty much the same.

It sounds like your are behind another router instead of connecting directly to the ISP. To test, disable DHCP on your router and connect to the lan socket using of the LAN ports. This will effectively turn your router into bridge mode and its just like an AP/switch. Set your PS4 to DHCP mode and see what IP address you are getting. If you get an internal IP address (eg. 192.168.x.x, you are confirm behind another router).

Sometimes, routers have problems working behind another router if your IP range is the same. If the LAN socket gives you 192.168.x.x, don't set your router to have the same for the LAN ports, try something like 10.86.x.x...
