CHAPTER 19 Universal Plug-and-Play (UPnP) 19.1 Overview 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. 19.1.1 What You Can Do in this Chapter The UPnP screen lets you enable UPnP on the Device (Section 19.3 on page 228). 19.2 What You Need to Know 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. 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 P-870HN-5xb User's Guide 227

Universal Plug-and-Play (UPnP)
19.1
Overview
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.
19.1.1
What You Can Do in this Chapter
The
UPnP
screen lets you enable UPnP on the Device (
Section 19.3 on page 228
).
19.2
What You Need to Know
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.
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
