Assigning Services (Http, Ftp - Technicolor TG789vac v2 Setup And User Manual

8.2 Assigning services (HTTP, FTP,...) to a computer
Introduction
The TG789vac v2 is designed to allow you to use one Internet connection for all devices that are connected to your local
network. This means that all your local devices share one public IP address as if only one local host would be connected to
the Internet.
Issue
When the TG789vac v2 receives an incoming message, the TG789vac v2 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 TG789vac v2
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 TG789vac v2 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
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 TG789vac v2 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 TG789vac v2.
