Chapter 14:

UPnP Screen

This chapter introduces the Universal Plug and Play feature of the WR1500.

14.1 Universal Plug and Play 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.

14.1.1 How Do I Know If I’m Using UPnP?

UPnP hardware is identiﬁ ed 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.

14.1.2 NAT Traversal

UPnP NAT traversal automates the process of allowing an application to operate through

NAT. UPnP network devices can automatically conﬁ gure 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 SUA/NAT chapter for further information about NAT.

14.2 Cautions with UPnP

The automated nature of NAT traversal applications in establishing their own services

and opening ﬁ rewall ports may present network security issues. Network information and

conﬁ guration may also be obtained and modiﬁ ed by users in some network environments.

All UPnP-enabled devices may communicate freely with each other without additional

conﬁ guration. Disable UPnP if this is not your intention.

14.3 Conﬁ guring UPnP

Click ADVANCED and then UPnP to display the screen shown on the next page.
