Enabling Universal Plug and Play (UPnP)

Universal Plug and Play (UPnP) can improve the overall networking experience through automatic discovery and device interoperability. 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.

By default, UPnP is disabled. When disabled, the router will not allow any device to automatically control the resources of the router; for example, port forwarding. When enabled, you must set the Advertisement Period and the Advertisement Time to Live according to the following criteria:

The UPnP Portmap Table shows IP addresses and other settings of UPnP devices that have accessed this wireless gateway. These settings are described in the following Portmap table.
