4.4.4. UPnP
UPnP offers peer-to-peer network connectivity for PCs and other network devices, along
with control and data transfer between devices. UPnP offers many advantages for users
running NAT routers through UPnP NAT Traversal, and on supported systems makes tasks
such as port forwarding much easier by letting the application control the required settings,
removing the need for the user to control advanced configuration of their device.
Both the user's Operating System and the relevant application must support UPnP in
addition to the router. Windows XP and Windows Me natively support UPnP (when the
component is installed), and Windows 98SE users may install the Internet Connection
Sharing client from Windows XP in order to support UPnP. Windows 2000 does not support
UPnP.
UPnP: Select this checkbox to activate UPnP. Be aware that anyone could use a UPnP
application to open the web configurator's login screen without entering the ADSL Modem
Series 's IP address
Auto-configured: Select this check box to allow UPnP-enabled applications to
automatically configure the ADSL Modem Series so that they can communicate through the
ADSL Modem Series, for example by using NAT traversal, UPnP applications automatically
reserve a NAT forwarding port in order to communicate with another UPnP enabled device;
this eliminates the need to manually configure port forwarding for the UPnP enabled
application.
