Upnp - D-Link Router User Manual

Section 3 - Configuration
UPnP (Universal Plug and Play) 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. UPnP broadcasts are only allowed on the LAN. UPnP is
often used for popular audio visual software. It allows automatic discovery of your device in the network. If you are concerned about UPnP security,
you can disable it.
