4.3 UPNP 
The  Universal  Plug  and  Play  (UPnP)  feature  allows  network  devices,  such  as 
computers  from  the  Internet,  to  access  resources  on  local  host  or  devices as 
needed.  UPnP-enabled devices  can  be  discovered  automatically  by  the  UPnP 
service  application  on  the  LAN.  If  you  use  applications  such  as  multiplayer 
gaming,  peer-to-peer  connections,  real-time  communications  such  as  instant 
messaging, or remote assistance (a feature in Windows XP), you may need to 
enable Universal Plug and Play (UPnP) for better experience. 
Click Advanced -> UPnP to enter the configuration screen. The UPnP feature is 
enabled by default.
