Tips From Sony

On the PS4 system's function screen, select (Settings) Remote Play Connection Settings, and then select the Enable Remote Play checkbox to set a checkmark.
On the PS4 system's function screen, select (Settings) PlayStationNetwork/Account Management Activate as Your Primary PS4 Activate.
When using an access point provided by a public WiFi service, set up your system so that it can connect to that access point.

Registering (pairing) a device
You can register one PS4 system on your system for remote play.

1.
Log in to the PS4 system.
When logging in to the PS4 system, select the user that is linked to the same Sony Entertainment Network account as your system.
2.
On your system, select (PS4 Link) Start Remote Play.
When registration is complete, the PS4 system's screen is displayed on your system.

Verify whether port 9304 (UDP) can be used. If that port cannot be used, you must adjust your router's port forwarding setting to allow communication to the PS4 system from the Internet. For details on the port numbers used for remote play and how to adjust settings, refer to the instructions supplied with your router.
If the PS4 system is connected to the Internet via two or more routers, communication may not work correctly.
A router is a device that allows multiple devices to share a single Internet line.
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.
Port forwarding is a function for forwarding signals that arrive at a specific port (entrance) to another specified port (exit). This is also referred to as "port mapping" or "address conversion."
