Table 52 Configuring UPnP
LABEL DESCRIPTION
Enable the Universal Plug
and Play (UPnP) feature
Select this checkbox to activate UPnP. Be aware that anyone could use
a UPnP application to open the web configurator's login screen without
entering the Prestige's IP address (although you must still enter the
password to access the web configurator).
Allow users to make
configuration changes
through UPnP
Select this check box to allow UPnP-enabled applications to
automatically configure the Prestige so that they can communicate
through the Prestige, for example by using NAT traversal, UPnP
applications automatically reserve a NAT forwarding port in order to
communicate with another UPnP enabled device; this eliminates the
need to manually configure port forwarding for the UPnP enabled
application.
Allow UPnP to pass through
Firewall
UPnP broadcasts are only allowed on the LAN. If you block LAN-to-
LAN/Prestige traffic using the firewall, then you need to select this
check box to allow UPnP-enabled traffic to pass through the firewall.
This setting remains active until you disable UPnP.Clear this check box
if you do not want to create a hole in the firewall for UPnP application
packets (for example, MSN packets).
Apply Click Apply to save your changes back to the Prestige.
Reset Click Reset to begin configuring this screen afresh.
