Chapter 22 UPnP
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the ZyWALL 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.

22.1.4 UPnP and ZyXEL

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

DESCRIPTION
This identifies the ZyXEL device in UPnP applications.
Select this check box to activate UPnP. Be aware that anyone could use a
UPnP application to open the web configurator's login screen without
entering the ZyWALL'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 ZyWALL so that they can communicate through the ZyWALL,
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.
Select this check box to allow traffic from UPnP-enabled applications to
bypass the firewall.
Clear this check box to have the firewall block all UPnP application packets
(for example, MSN packets).
