Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,
access the network and connect to other devices as needed. UPnP devices can
automatically discover the services from other registered UPnP devices on the network.
If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time
communications such as instant messaging or remote assistance (a feature in Windows XP),
you should enable UPnP
.
To turn on Universal Plug and Play:
Select Advanced >
Advanced Setup > UPnP. The UPnP screen displays.
The available settings and information in this screen are:
Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration.
The default setting for UPnP is disabled. If this check box is not selected, the modem
router does not allow any device to automatically control the resources, such as port
forwarding (mapping) of the modem router.
