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-416N 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.
