Firewall Settings for Playstation 3, PS3 Firewall Ports
If your PlayStation 3 is operating slow, losing connection, or just not working right most of the time the chances are that you need to change some settings on your Internet router or firewall. Routers use NAT(Network Address Translation) to allow multiple devices to function behind the router as if they all have the public address that your ISP(Internet Service Provider) has provided to you. The PS3 requires various ports to be open to communicate with other users online as well as other ports to be opened to the PlayStation 3 for other games to function properly. Below I list these ports required for the PS3 to operate, ports required for certain games to operate, and followed by a brief explanation of what you need to look for in terms of configuring your router or firewall.
