4.2.14 UPnP 
With UPnP (Universal Plug and Play) function, the host in LAN can 
request the Router to carry specific port forwarding, thus the external 
host can access the internal host for resources. For example, the MSN 
Messenger under Windows XP and Windows Me can utilize UPnP in 
video and audio communication, thus the function restricted by NAT can 
restore its normal use. Enable UPnP to help support applications that 
would not otherwise work behind a Router. Both UPnP Internet 
Gateway Device and NAT Traversal are supported.
