Chapter 19 Universal Plug-and-Play (UPnP)
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the NBG460N 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.

19.2 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 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 NBG460N'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 NBG460N so that they can communicate
through the NBG460N, 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).
