Configuring the Advanced Settings

Using UPnP (Universal Plug and Play)

PCs with UPnP (Universal Plug & Play) can offer their own network services and automat- ically use services offered on the network.

Please remember:

The PC must have Windows ME or Windows XP as its operating system. Check whether the UPnP function has been installed in your PC's operating system. It may be neces- sary to retrospectively install the UPnP components even on Windows XP or Windows ME systems. Please consult your PC's operating instructions.

As soon as you have installed UPnP in the operating system of a PC and activated it on the router, applications on this PC (for example Microsoft Messenger) can communicate via the Internet without your needing to expressly authorise it. In this case, the router automatically implements port forwarding (Port Forwarding, see page 88), thereby facilitating communication via the Internet.

You will see a symbol for your Gigaset SX541 WLAN dsl on the task bar on the PC on which UPnP is installed. Windows XP systems will also include the icon under network connections. Clicking on this icon opens the Gigaset SX541 WLAN dsl's configuration screens.

ì In the Advanced Settings – Internet menu, select Internet Connection. ì Select UPnP.

Please remember:

When the UPnP function is active, system applications can assign and use Ports on a PC. This can be a security risk.
