See the Network Address Translation (NAT) chapter in your User's Guide for further information about
NAT.
8.1.3 Cautions with UPnP
The automated nature of NAT Transversal 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.
8.2 UPnP and ZyXEL
ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum Creates UPnP™
Implementers Corp. (UIC). ZyXEL's UPnP implementation supports IGD 1.0 (Internet Gateway Device). At
the time of writing ZyXEL's UPnP implementation supports Windows Messenger 4.6 and 4.7 while
Windows Messenger 5.0 and Xbox are still being tested.
UPnP broadcasts are only allowed on the LAN.
Please see later in this Users Guide for examples of installing UPnP in Windows XP and Windows Me as
well as an example of using UPnP in Windows.
