PlayStationNetwork blocking of CGNAT public addresses

Tue Sep 20 15:33:17 UTC 2016

PSN is one reason I am not a fan of CGNAT. All they see are tons of connections from the same IP.  This results in them banning folks.  Due to them being hacked so many times getting them to actually communicate is almost impossible.  My .02 is just get the gamers a true public if at all possible.
