Easiest Way to Get an Open Port on the Thomson Alcatel ACG905 Router
Thomson-Alcatel ACG905 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 ACG905 router.
- Navigate to the port forwarding section.
- Click the Router link.
- Click on Forwarding.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Thomson-Alcatel ACG905 router.

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 ACG905 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 192.168.100.1 in it. Just replace all of that with the IP address of your Thomson-Alcatel ACG905 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: 192.168.100.1
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 ACG905 Router Username is: blank
- The Default Thomson Alcatel ACG905 Router Password is: admin

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 Router link near the top of the page.
The menu on the left should change. In this new menu, click Forwarding.
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:
You need to name this entry in the Application Name box. The name does not make any difference in the forward; it's just there so that you can remember later why you setup this forward.
Put the port to forward into the Source Port and Destination Port box.
Use the Protocol dropdown box to select the protocol type of the ports you are forwarding.
Enter the IP address to forward these ports to into the IP Address box. If you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box.
When you are done click the Plus button.
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 ACG905 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.
