7.2 UPnP Setup

The DSL device supports a control point for Universal Plug and Play (UPnP) version 1.0, and

supports two key features: NAT Traversal and Device Identification. This feature requires one active

WAN interface. In addition, the host should support this feature. In the presence of multiple WAN

interfaces, select an interface on which the incoming traffic is present.

With NAT Traversal, when an UPnP command is received to open ports in NAT, the application

translates the request into system commands to open the ports in NAT and the firewall. The

interface to open the ports is given to UPnP when it starts up and is part of the configuration of the

application.

For Device Identification, the application will send a description of the DSL device as a control point

back to the host making the request.
