Chapter 18 Universal Plug-and-Play (UPnP)
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.
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 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).
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.
