Chapter 18 Universal Plug-and-Play (UPnP)
AMG1302-T10A User’s Guide
188
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the 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.

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 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 Device so that they can communicate through the 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.
