Standards defined by the [UPnP Forum|http://www.upnp.org/] for home networking.

UPnP lets you run a network service behind a [NAT] device, and have your device communicate with the [NAT] device to automatically set up a pinhole from the external network to the internal server.  This lets you run [MSN] Messenger and transfer files.

Generally considered insecure, because people rely on NAT to provide network security, and you don't want your users being able to create tunnels to potentially unpatched machines!  On the flipside NAT's pretty insecure anyway, people can use things like [Teredo] to bypass NAT's "security".  If you want security use a proper stateful [FireWall], not NAT.

Implemented by (among other things) Windows XP's Internet Connection Sharing and the Dynalink RTA220 [ADSL] modem.
