4.6.4 UPnP

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 on 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.
