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 98 users may install the Internet Connection Sharing client from Windows XP in order to support UPnP. Windows 2000 does not support UPnP.

Enable the Universal Plug and Play (UPnP) Service: Select this checkbox to activate UPnP. Be aware that anyone could use an UPnP application to open the web configuration’s login screen without entering the ADE-3400/4400's IP address.

Allow users to make configuration changes through UPnP: Select this check box to allow UPnP-enabled applications to automatically configure the ADE-3400/4400 so that they can communicate through the ADE-3400/4400. 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.
