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
