I have opened all the ports and even put my ps4 on DMZ and nothing seems to work. In other games I have no problem playing multiplayer but in Destiny I have to have a friend in my fireteam to be able to even search for a match in the crucible otherwise it just says "searching for guardians" and "evaluating guardians" forever. Before anyone says anything yes I do have Playstation subscription. I have Nat2 aswell. I love Destiny but playing alone all the time is rather lonely.
