Port Forwarding

Make sure your Windows 11 computer is connected directly to Internet Service Provider Cable Modem/Router.

Open Command Prompt. Go to the search icon and type “cmd” in the search bar.

Type "ipconfig" when cmd opens and press enter. This will show the computer's unique IP address “IPv4” and “Default Gateway Address”. That is the Cable Modem/Router IP address and the "IPv6" IP address. Take note of all these numbers: “IPv4,” “Default Gateway," and "IPv6". Close the Command Prompt window.

Go to any browser and type in the search bar the “Default Gateway” IP address. You need to Google search the website for the default Username and Password for your device, or you can call your Internet Service Provider to give you the credential of your device.#*The default gateway IP address for Technicolor is, for example, “192.168.0.1.” The Technicolor page will ask for the Username and Password. By default, the username and password for the Technicolor model are both blanks.

Go to the default page of the Technicolor device. Click on the “Connection” tab. Click on “Devices” to search for your computer name or the IP address “IPv4” that was saved from Command Prompt. Click on the pencil icon of your windows 11 computer to enter the editing mode window.

Click on the Reserved IP option. This will reserve the same IP address on your computer. Click on OK when done.

Go to the Application tab to access the Port Forward table page. Click the “Port Forward” tab to show you Port Forward Table.

Click on the plus sign on the right side of the Port Forward table to set up the port forward. Under Start Port, type the unique number of the port that you saved. By default, it is “3389.” In this case, the unique port is “15275” Under End Port, type the same unique port number, default “3389”. Under Type, just choose the option “TCP” or “BOTH”. Under Server IP, insert the computer IP address “IPv4” that you have saved from the “Command Prompt”. Under “Server IPv6”, right-click your mouse and click paste to insert the “IPv6” that you have saved from the "Command Prompt" section. Click on the “Enable” switch button to enable the port forwarding of your Remote Desktop. Click “Save” when done. You can exit your Cable Modem/Router page and close it.

Make sure to get the Public IP address from your Windows 11 computer. Open any browser and type “what’s my public IP.” There will be quite a few websites that will provide you with your public IP address “IPv4”. You can use https://whatismyipaddress.com/ to get your public IP address. Take a note of that IP address “IPv4” to use it for the next part. By now, the Remote Desktop feature has been completed and enabled in the Windows 11 Computer.
