21.10 UPnP
Universal Plug and Play (UPnP) makes it possible to use current messenger services (e.g.
real time video/audio conferencing) as peer-to-peer communication where one of the peers
lies behind a NAT-enabled gateway.
UPnP enables (mostly) Windows-based operating systems to take control of other devices
with UPnP functionality on the local network. These include gateways, access points and
print servers. No special device drivers are needed as known common protocols are used,
such as TCP/IP, HTTP and XML.
Your gateway makes it possible to use the subsystem of the Internet Gateway Device
(IGD) from the UPnP function range.
In a network behind a NAT-enabled gateway, the UPnP-configured computers act as LAN
UPnP clients. To do this, the UPnP function on the PC must be enabled.
The pre-configured port used for UPnP communication between LAN UPnP clients and the
gateway is
.
. The LAN UPnP client acts as a so-called service control point, i.e. it re-
cognizes and controls the UPnP devices on the network.
The ports assigned dynamically by, for example, MSN Messenger, lie in the range from
