P-334WH User's Guide
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the ZyXEL Device allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if this is not your intention.

17.2 UPnP and ZyXEL

ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP™
Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device
(IGD) 1.0.
See the following sections for examples of installing and using UPnP.

DESCRIPTION
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 ZyXEL Device's IP address (although you must still enter the password to
access the web configurator).
Select this check box to allow UPnP-enabled applications to automatically
configure the ZyXEL Device so that they can communicate through the ZyXEL
Device, 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.
