Assigning a service (HTTP, FTP,...) to a Computer
Introduction
The MediaAccess Gateway 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 MediaAccess Gateway receives an incoming message, the MediaAccess Gateway 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 MediaAccess
Gateway 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 MediaAccess Gateway 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 MediaAccess Gateway 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 MediaAccess Gateway.
For more information on UPnP, see
“8.1 UPnP” on page 66
.

Assign a game or application to a local networking device
If you assign a game or application to a local networking device, you will basically tell the MediaAccess Gateway that if it
receives requests for a specific game or application, it has to forward these messages to a specific computer.
Proceed as follows to do so:
1
Browse to the MediaAccess Gateway GUI.
For more information, see
“Accessing the MediaAccess Gateway GUI” on page 33
.
2
On the
Toolbox
menu, click
Game & Application Sharing
.
3
In the
Pick a task
list, click
Assign a game or application to a local network device
.
4
In the
Game or application
list, click the service you want to run on the computer. For example,
HTTP Server (World
Wide Web)
.
5
In the
Device
list, select the computer to which you want to assign the service. Your computer will be listed with its
computer name.
6
All incoming requests for the selected service will now be directed to the selected device. The MediaAccess Gateway will
also configure its firewall to allow this service.
If the service is not available in the list, click
Create a new game or application
in the
Pick a task
list. For more
information, click
Help
on the
MediaAccess Gateway GUI
.
