4.5.2 Game & Application Sharing

Overview

The Overview page summarizes the applications or games installed on a particular 
local host on your network, for which the SpeedTouch™ should accept inbound 
initiated connections coming from the Internet.

Configure

On the Configure page, you can:

Select Use UPnP to enable UPnP on the SpeedTouch™.
UPnP provides NAT-Traversal: UPnP aware applications on a PC will 
automatically create Hyper-NAT entries on the SpeedTouch™ for incoming 
traffic on the protocol ports this type of traffic needs. As a consequence these 
applications are able to traverse the SpeedTouch™ without the need for extra 
and manual configuration.

For security reasons you are able to configure the UPnP policy towards 
Windows XP and UPnP aware applications and Operating Systems.

In case you select the Use Extended Security check box, only limited UPnP 
operation between a host running MS Windows XP and the SpeedTouch™ is 
allowed: A local host is:

NOT allowed to connect/disconnect the SpeedTouch™ Internet Gateway 
Device (IGD) connection.

Allowed to add/delete Hyper-NAT entries only for its own IP address, not 
for other local hosts.

If you clear the Use Extended Security check box, all UPnP- and IGD-based 
communication between any local host and the SpeedTouch™ is allowed.

UPnP is an architecture for transparent peer-to-peer connectivity of 
computers, intelligent appliances, and (wireless) devices. It enables 
seamless operation of a wide range of games and messaging 
applications.
