Opening Ports on the Thomson Alcatel TG784

This Thomson Alcatel TG784 router has a basic firewall that helps protect your home network from unwanted Internet access. The firewall does this by blocking the incoming and outgoing connections to the Internet unless a rule is created that states otherwise. Sometimes an online game or application needs additional rules. To open additional connections you need to create a port forward.

In this guide I will show you exactly how to open ports on the Thomson Alcatel TG784 router. These steps include:

  1. How to setup a static IP address on the exact device you plan on forwarding these ports to.
  2. How to login to the Thomson Alcatel TG784 router.
  3. How to find the port forwarding section of the router.
  4. How to enter the port forward information.


We think that forwarding a port should be easy. That's why we created Network Utilities. Our software does everything that you need to forward a port.

When you use Network Utilities you get your port forwarded right now!

Step 1

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.

  • Recommended - Our free program will setup a static IP address for you.
    Download Network Utilities today!

  • Or follow our Static IP Address guide to setup a static IP address.


TIP: Write this static IP address down. You need it a little later in this guide.

Step 2

It is now time to login to the Thomson Alcatel TG784 router. This router has a web interface meaning you login using a web browser. This can usually be any web browser you choose. Simply pick your favorite. Some common options are Chrome, Internet Explorer, and Firefox.

After you have opened the web browser of your choice, find the address bar. It will look like this:

192.168.1.254

We have circled the address bar in the image above. It has 192.168.1.254 in it. Replace what is currently in the address bar with the router's IP address.

TIP: The router's IP address can also be called the router's GUI address or the computer's default gateway.



The default Thomson Alcatel TG784 router IP address is: 192.168.1.254



Press the Enter key on your keyboard after you have finished entering the router's IP address in the address bar. You should be shown a authentication page like the one below:

If you are not shown a page asking for a username and/or password you probably entered the wrong IP address. This can be due to several different reasons. Find out what your router's IP address is by following the instructions on this How To Find Your Router's IP Address page.

You should see a box prompting you for your username and password.



  • The Default Thomson Alcatel TG784 Router Username is: none
  • The Default Thomson Alcatel TG784 Router Password is: none


Enter your username and password, and then click the Login button to log in to your Thomson-Alcatel TG784 router.

Thomson Alcatel Usernames and Passwords

This is a common place to get stuck. Here are a few things you can try:

First, try other Thomson Alcatel usernames and passwords. If you have a slightly different firmware version you could have a different username and/or password as well. Here is our list of the Default Thomson Alcatel Router Passwords.


The most common reason for a username/password combination not work is because it was changed in the past. Try guessing a few times or just use our Router Password Cracker. This automates the guessing process for you.


Finally if you are still stuck after trying both of the above options, it may be time to consider a factory reset. Do not reset your router unless you have exhausted your other troubleshooting methods. Every setting you have ever changed is erased so a full reconfiguration of your router is needed. Learn the basics of resetting a router in this How to Reset a Router guide.

Step 3

It is now time to find the port forwarding section of the router interface. To do that we will start on the Home page:

Begin by clicking the Toolbox option in the left sidebar.

A new set of links will appear at this point. Pick the option of Game & Application Sharing.

Now look to the bottom of the page under Pick a task... Choose the link titled Create a new game or application.

On this new page, enter the name of the program or game in the Name box. It doesn't really matter what you enter in this box, just enter something that will remind you why you forwarded these ports.

Then, put a dot in the Manual Entry of Port Maps radio button.

Finally, click the Next option to continue.

You are now on the correct page to do some port forwarding.

Step 4

It is time to enter some data into your router so you can get your ports forwarded. To help you with this step, we need you to answer two questions:

Application :
IP Address :

(Remember that Static IP address I had you write down in Step 1? You need to enter that in the IP address box above.)

This next section is our router simulator. It will show you what data to enter based on your choices above. Right now we are showing the ports for XBox Live. Simply fill in the boxes in your router as you see them here.

After entering the above information into your router, click the Assign a game or application to a local network device.

You should now see a page like the one above. Find Device near the bottom of the page and use the drop down list to choose the device you are forwarding these ports to. This box will contain all the devices currently visible on your network.

Now use the Game or Application drop down menu to pick the application you created earlier.

Finally, click the Add button to enable the port forward.

That's it, you are finished!


Testing the Port Forward

In order to quickly find out if the port forward you just completed on the Thomson Alcatel TG784 router went through correctly we recommend using a Open Port Checker. If you use our Network Utilities tool, it includes a free Open Port Checker. Our Open Port Checker is the only one online that has Guaranteed Results.

Wait, there's more...

If you are still having trouble with port forwarding, use our Port Forwarding Software. It is and easy and fast way to get your port forwarded.
