Please do ask about all the ports needed to open to play the game fully. Seems there is an issue with most if not all Zyxel and Thompson router users mainly. I just started playing the game when it came via PS+ and I REALLY LIKE IT! It just bums me out that i cannot connect to UNX and there fore can't play any PvP related content or weekly missions etc. and i am restricted to play co-op only with friends. Watching this topic very actively and thanks for doing some digging, I'm sure many people will be happy if we find a solution via port opening or maybe a incoming patch. Keep it up!
