229 Chapter 18 UPnP
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if this is not your intention.
18.2 UPnP and ZyXEL
ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum Creates
UPnP™ Implementers Corp. (UIC). ZyXEL's UPnP implementation supports IGD 1.0
(Internet Gateway Device). At the time of writing ZyXEL's UPnP implementation supports
Windows Messenger 4.6 and 4.7 while Windows Messenger 5.0 and Xbox are still being
tested.
UPnP broadcasts are only allowed on the LAN.
Please see later in this User’s Guide for examples of installing UPnP in Windows XP and
Windows Me as well as an example of using UPnP in Windows.

The following table describes the labels in this screen.
Table 96 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.
