6.4.1.2 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 be obtained
and modified by users in some network environments.
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if you don't want this to occur.
UPnP broadcasts are only allowed on the LAN.
See later sections for examples of installing UPnP in Windows XP and Windows Me as
well as an example of using UPnP in Windows.

6.4.1.3 Configuring UpnP

The following table describes the labels in this screen.

UPnP
Auto-configured
Auto-configuration allows UPnP-enabled applications to automatically configure the
DSL-2120/2120W so that they can communicate through; this eliminates the need to manually
configure port forwarding for the UPnP enabled application. When you are done making
changes, click on SAVE to save your changes.
