7.2 Assigning a service (HTTP, FTP,...) to a Computer
Introduction
The TG589vn v3 allows you to use one Internet connection for multiple computers. This means that all your computers
share one public IP address, as if only one computer were connected to the outside world.
Issue
When the TG589vn v3 receives an incoming message, the TG589vn v3 has to decide to which computer it has to send this
message.
If the incoming message is a response to an outgoing message originating from one of your computers, the TG589vn v3
sends the incoming message to this computer.
If your are running a server or an application that acts as a server (for example a HTTP server, Internet game), the initial
message will come from the Internet and the TG589vn v3 has no information to decide to which computer it should forward
the incoming message.
Solution
To avoid this problem you can do either of the following:

Enable UPnP .

Assign a game or application to a local networking device .
UPnP
UPnP is a technology that enables seamless operation of a wide range of games and messaging applications. Your computer
will use UPnP to communicate to the TG589vn v3 which services are running on the computer.
For example, when you start a UPnP-enabled application on your computer, it will automatically create the necessary port
mappings on this computer and on the TG589vn v3.
For more information on UPnP, see “7.1 UPnP” on page 53 .
