8.4 UPnP
This section describes the NAT > UPnP page.
The Universal Plug and Play (UPnP) is architecture that implements zero configuration
networking, that is, it provides automatic IP configuration and dynamic discovery of the
UPnP compatible devices from various vendors. A 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, a 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 Port Forwarding 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.
