If you are able to connect to the Internet but cannot get into Sony Computer Entertainment America's (SCEA) game servers or network, it may be a firewall issue. A firewall is a security product that employs a combination of hardware and software to prevent unauthorized users or Internet traffic from gaining access into a private local area network (LAN) or personal computers. These settings will need to be entered into your router.
Below are the TCP and UDP (firewall) port numbers you will need to connect online with PlayStation® products.
