18.1.3 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 ZyXEL 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.
18.2 UPnP and ZyXEL
ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP™
Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device
(IGD) 1.0.
