UPnP
UPnP (Universal Plug-and-Play) is a technology that offers seamless
operation of voice messaging, video messaging, games, and other
applications that are UPnP-compliant. Some applications require
the Router's firewall to be configured in a specific way to operate
properly. This usually requires opening TCP and UDP ports and in
some instances setting trigger ports. An application that is
UPnP-compliant has the ability to communicate with the Router,
basically "telling" the Router which way it needs the firewall
configured. The Router ships with the UPnP feature disabled. If
you are using any applications that are UPnP-compliant, and wish
to take advantage of the UPnP features, you can enable the UPnP
feature. Simply select "Enable" in the "UPnP Enabling" section of the
"Utilities" page. Click "Apply Changes" to save the change.
