UPnP is a network protocol that allows devices to share files and printers. When UPnP is enabled on a PS4, it can allow other devices on the network to access your PS4’s files and printers. This can be a great feature if you want to share files with friends or family, but it can also be dangerous if you don’t know how to disable UPnP on your PS4. To disable UPnP on your PS4, you’ll need to find the following information: -The name of the device that you want to disable UPnP for (e.g. “PS4” in this example) -The IP address of the device (e.g. 192.168.1.10 in this example) -The port number that the device is using (e.g. 9200 in this example) -The command line that will start up the UPnP server on the device (e.g.“upnp” in this example) Once you’ve found these information, you’ll need to type the following command into a text editor: “upnp -disable” This will disable UPnP on the device for specified IP address and port number
