[quote]disable all hardware firewalls[/quote] Hahaha HAHAHAHHAHAHAHAHAH [quote]you cannot use voice chat with ____ when you're using the same ps4 as them[/quote] Will come up the second you piss a person who knows the basics of coding off. With a firewall they'd have a good bit more trouble, but it sure does cut off the little guys from being morons. [spoiler]of course, anyone who knows what they're doing can easily bypass a firewall on a router, just those who don't know their stuff will fail [/spoiler] Know this from experience getting my router screwed to oblivion by someone who knew what they where doing.
