Was reading this blog http://blog.us.playstation.com/2015/04/14/bloodborne-sells-one-million-first-1-03-details/ and it says that anything less than NAT Type 3 may hinder gameplay, but I don't quite understand what that means. Im running the latest 3xx.52_2 firmware, and have Nat and UPNP enabled, but even when I place the Ps4 in the DMZ it still says Nat type 2. Anyone have any ideas?
