4.3.4 UPnP
UPnP (Universal Plug and Play) allows several devices (such
as routers, televisions, stereo systems, game consoles, and
cellular phones), to be controlled via an IP-based network with
or without a central control through a gateway. UPnP connects
PCs of all form factors, providing a seamless network for remote
configuration and data transfer. Using UPnP, a new network device
is discovered automatically. Once connected to the network,
devices can be remotely configured to support P2P applications,
interactive gaming, video conferencing, and web or proxy servers.
Unlike Port forwarding, which involves manually configuring
port settings, UPnP automatically configures the router to accept
incoming connections and direct requests to a specific PC on the
local network.
