Like I mentioned, I'm pretty noob at the game and server hosting in general, my bad, I believe this is the full log: https://pastebin.com/qMgeFCqA
I haven't found a way to set a specific public port. The public ports are selected automatically when choosing a process name, it seems like that is the way this router works, although I've never used this type of router before, Router name is hitron cgnv5.
