How to Port Forward a Thomson Alcatel TG787 Router
Thomson-Alcatel TG787 routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.
The basic process to open a port is:
- Setup a static IP address on either your computer or device that you want to forward a port to.
- Login to your Thomson Alcatel TG787 router.
- Navigate to the port forwarding section.
- Click the Toolbox button.
- Click the Game & Application Sharing link.
- Click the Create a new game or application link.
- Enter a name in the Name box.
- Click the Manual Entry of Port Maps radio button.
- Click the Next button.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Thomson-Alcatel TG787 router.

It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.

- Or follow our Static IP Address guides to setup a static IP address.
After setting up a static ip address on your devices you need to login to your router.
Now we are going to login to your Thomson-Alcatel TG787 router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.
Open up your web browser and find the address bar. It should look something like this:
In the picture above the address bar has 192.168.1.254 in it. Just replace all of that with the IP address of your Thomson-Alcatel TG787 router. Your router's IP address can also be refered to as your computer's default gateway.
By default the IP address is set to: 192.168.1.254
After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:
You should see a box prompting you for your username and password.
- The Default Thomson Alcatel TG787 Router Username is: unknown
- The Default Thomson Alcatel TG787 Router Password is: unknown
Enter your username and password, and then click the Login button to log in to your Thomson-Alcatel TG787 router.

If you still can't login to your router because you forgot your Thomson-Alcatel TG787 router username and password, use our How to Reset a Router Password guide to set your Thomson-Alcatel TG787 router back to its factory settings.
Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the first page in your router:
Click the Toolbox button near the left of the page.
Click the Game & Application Sharing link near the left of the page.
Click the Create a new game or application link near the bottom of the page.
Enter the name of the program into the Name box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded would be a good idea.
Put a dot into the Manual Entry of Port Maps radio button.
Click the Next button near the bottom of the page.
Here are the ports to forward for Xbox Live:
TCP Ports: 3074 UDP Ports: 3074
If you are looking for the ports for a different application you can find it by either:
Select the protocol type of the ports you are forwarding from the Protocol box.
If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Translate To, Top Port Range box and the highest number of that range into the Bottom Port Range box. If you are only forwarding a single port number then enter that number into both the Translate To, Top Port Range and the Bottom Port Range boxes.
Click the Add button when you are finished.
Click the Assign a game or application to a local network device link near the bottom of the page.
Use the Device box to choose a device to forward ports to. This box contains a list of device names that are visible on your network.
Select the application you created using the Game or Application drop down box. Then click Add to enable it.
Your ports should now be open. It is time to test them.
Test if Your Ports are Open
Now that you have forwarded ports on the Thomson-Alcatel TG787 you should test to see if your ports are forwarded correctly.
To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Check tool is the only online port checking tool with Guaranteed Results.
