UPnP
The DSL router 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.
