Upnp Screen - ZyXEL Communications NBG-417N User Manual

Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
firewall ports may present network security issues. Network information and configuration may also
be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the NBG-417N 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.

NBG-417N User's Guide
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 NBG-417N'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 NBG-417N so that they can communicate
through the NBG-417N, 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.
Click Apply to save the setting to the NBG-417N.
Click Reset to begin configuring this screen afresh.
