The Upnp Screen - ZyXEL Communications P-660H-61 User Manual

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.
