23.1 Overview

This chapter introduces the UPnP feature in the web configurator.
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
