Enabling Universal Plug and Play (UPnP)
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.
On the main menu, select UPnP. The UPnP screen displays.
UPnP can be enabled or disabled for automatic device configuration. The Enable UPnP check
box is selected by default. If you clear this check box, and click Apply, the modem router will not
allow any device to automatically control the resources, such as port forwarding (mapping), of the
modem router.
