Re: Major ping, everything unplayable.. Please help!
Not sure any apps exist for the PS4 but you could grab a router with VPN client built in to it (I use an Asus AC86U which does). Then you can set the router to connect to the VPN and even specify the IP of the PS4 if you only want that to go through it - at least using the Merlin firmware. Expensive option though if you need more hardware..
