Assigning a service (HTTP, FTP,...) to a computer
Introduction
The Thomson 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 is connected to the outside world.
Problem
When the Thomson Gateway receives an incoming message, the Thomson Gateway has to decide to which
computer he will have to send this message.
If the incoming message is a response to an outgoing message originating from one of your computers, the
Thomson 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 Thomson Gateway has to decide to which computer
he should forward the incoming message.
In the latter case, the Thomson Gateway cannot decide all along the service related to the message is not
assigned to one computer.
Solution
To avoid this problem you can:
±
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 Thomson Gateway which services are running on the
computer.
For example, when you start a UPnP-enabled application on your computer, it will automatically creat the
necessary port mappings to this computer.
For more information on UPnP, see
”4.1 UPnP” on page 26
.
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 Thomson 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
Thomson Gateway GUI
.
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 request for the selected service will now be directed to the selected device. The Thomson
Gateway automatically configures the 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
Thomson Gateway GUI
.
The computer must be connected to the network and up and running.
It may be advised to assign “
Always use the same address
” or to configure the computer with
a static IP!

Dynamic DNS
Introduction
The dynamic DNS service allows you to assign a fixed DNS host name (for example john.dyndns.org) to a
broadband connection even if this connection is using a dynamically assigned IP address. As soon as the
device gets a new IP address, the dynamic DNS server updates its entry to the new IP address.
What you need
Before you can configure dynamic DNS, you first have to create an account at a dynamic DNS service
provider. For example:
±
www.dyndns.org
±
www.no-ip.com
±
www.dtdns.com
Procedure
Proceed as follows:
1
Browse to the
Thomson Gateway GUI
.
2
On the
Toolbox
menu, click
Dynamic DNS
.
3
On the
Location bar
, click
Configure
.
4
Select the
Enabled
check box.
5
Type the user name and password of your Dynamic DNS service account in the corresponding fields.
6
In the
Service
list, click the name of your Dynamic DNS service provider.
7
In the
Host
box, type the host name that you got from the Dynamic DNS service provider (for example
mywebpage.dyndns.org).
8
Click
Apply
