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. 
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 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.
See later sections for examples of installing UPnP in Windows XP and Windows Me as well as 
an example of using UPnP in Windows.
