UPnP (Universal Plug and Play) is a service that allows clients in the local network to automatically configure some devices and services.
This chapter of the user manual provides an overview of the UPnP page in TRB255 devices.
Note: UPNP is additional software that can be installed from the Services → Package Manager page.
If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode", which is located at the top-right corner of the WebUI.
