The Upnp Screen - ZyXEL Communications P-793H v3 User Manual

When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the P-79X 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.

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 P-79X'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 P-79X so that they can communicate
through the P-79X, 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.
