So I have recently tried to open some ports on my XR500 router for my PS4 and after assigning a static IP and forwarding my ports I checked the port map and only see one port opened (9308) and it is not even a port that I have in the list. I'm confused as to why this port is evening showing up on the port map. When I looked up the port it says that it is related to the playstation network. I'm not sure if I am doing the correct steps to open the ports but from what I have read online it seems like this has been an issue for this router showing those ports. Any input would be appreciated.
