ZyXEL Communications P-660H-Tx v2 - Manual (Page 182)

When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the ZyXEL Device allows multicast messages only on the LAN.
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if this is not your intention.
You must have IIS (Internet Information Services) enabled on the Windows web server for
UPnP to work.
15.2 UPnP and ZyXEL
ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP™
Implementers Corp. (UIC). ZyXEL's UPnP implementation supports IGD 1.0 (Internet
Gateway Device).
See the following sections for examples of installing and using UPnP.

LABEL DESCRIPTION
Active the Universal Plug
and Play (UPnP) Feature
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 ZyXEL Device'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 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.
