6.12 UPnP Screen
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple
peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network,
obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a
device can leave a network smoothly and automatically when it is no longer in use.
Use the following screen to enable UPnP on your LTE4506. To access this screen, click Router > Firewall >
