When you cannot connect to PlayStation™Network
When using PlayStation™Network at the office or other locations with shared networks, a firewall or other security measures might prevent you from connecting to PlayStation™Network. If this occurs, the following reference information might help you make a connection.
With PlayStation™Network, you connect with a PlayStation™Network server via the Internet or connect directly with other PS Vita systems and PS TV systems. The port numbers used to connect with the PlayStation™Network servers via the Internet are:
- TCP: 80, 443, 465, 993, 3478, 3479, 3480, 5223, 8080
- UDP: 3478, 3479
At other times, for example when competing with other players in an online game, you connect directly with other PS Vita systems and PS TV systems. A different port number is used each time you connect.
Communication might be restricted depending on the security functions provided by your router or Internet service provider. Refer to the instructions supplied with the network device in use, and information from your Internet service provider.
