23.3.2 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-419N 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.

enter the password to access the web configurator).
Click Apply to save the setting to the NBG-419N.
