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 
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 hardware is identified as an icon in the Network Connections folder 
(Windows XP). Each UPnP compatible device installed on your network will appear 
as a separate icon. Selecting the icon of a UPnP device will allow you to access the 
information and properties of that device. 

UPnP NAT traversal automates the process of allowing an application to operate 
through NAT. UPnP network devices can automatically configure network 
addressing, announce their presence in the network to other UPnP devices and 
enable exchange of simple product and service descriptions. NAT traversal allows 
the following:

• Dynamic port mapping
• Learning public IP addresses
• Assigning lease times to mappings

Windows Messenger is an example of an application that supports NAT traversal 
and UPnP.
