I have no software firewall; my computer has connected to PS just fine until I logged in from here. My roommate has a firewall on the router, and various ports need to be 'allowed' for them to work. I asked him to allow 7777 and he told me he had done so, but I still find the server unavailable when I attempt to log in. Pinging it, my computer can detect the server; I am not, however, able to connect to the game. Is port 7777 accurate? Is there something else I might try?
