Universal Plug-and-Play (UPnP)
This chapter introduces the UPnP feature in the web configurator.
12.1 Introducing Universal Plug and Play
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.
See
for configuration instructions.
12.1.1 How do I know if I'm using UPnP?
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.
12.1.2 NAT Traversal
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.
See the NAT chapter for more information on NAT.
12.1.3 Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services may
present network security issues. Network information and configuration may also be obtained
and modified by users in some network environments.
