devices from various vendors. An UPnP compatible device can dynamically join a network, obtain
an IP address, announce its name, convey its capabilities upon request, and learn about the
presence and capabilities of other devices on the network.
The Device can implement NAT traversal by enabling UPnP. When you enable UPnP, the Device
allows any LAN UPnP-enabled device to perform a variety of actions, including retrieving the public
IP address, enumerate existing port mappings, and add or remove port mappings. By adding a port
mapping, an UPnP-enabled device opens the related service ports on the Device to allow the
Internet hosts access. Windows Messenger is an example of an application that supports NAT
traversal and UPnP.
The Device provides the UPnP List , which lists all the port forwarding rules established using UPnP.
You can view each port forwarding rule’s detailed information in the list, which includes internal IP
address, internal port, protocol, remote IP address, external port, and description.
