Are there any cautions about 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.
All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable
UPnP if this is not your intention.
Opening UPnP
In the web configurator, click UPnP.
