Thomson-Alcatel TWG-870 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:
While these steps might seem difficult at first, we will walk you through each step for your Thomson-Alcatel TWG-870 router.
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!
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.
Now we are going to login to your Thomson-Alcatel TWG-870 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 192.168.0.1 in it. Just replace all of that with the IP address of your Thomson-Alcatel TWG-870 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: 192.168.0.1
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.
Enter your username and password, and then click the Login button to log in to your Thomson-Alcatel TWG-870 router.
If your username and password do not work then please visit our Default Thomson-Alcatel Router Passwords page.
If you still can't login to your router because you forgot your Thomson-Alcatel TWG-870 router username and password, use our How to Reset a Router Password guide to set your Thomson-Alcatel TWG-870 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 Advanced link near the top of the page.
The menu on the left should change. In this new menu, click Forwarding.
Now we are ready to enter some data in your router. In order to show you exactly how to configure your router we need you to answer 2 questions:
(The IP Address to forward to should be the same "static ip address" that you setup above)
Our router simulator shows you exactly what data to enter in your router based on your choices above. We are currently showing the ports for XBox Live. You should fill out the boxes in the router as you see them here:
When you're finished, click Apply near the bottom of the screen to save your changes.
Now that you have forwarded ports on the Thomson-Alcatel TWG-870 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.Thomson-Alcatel TWG-870 Router Screenshots.
