An important aspect of having a Technicolor router on your home network is internet security. In general, routers block incoming internet connections and protect your network by only allowing the connections that you specifically set up. Sometimes it is necessary to unblock certain connections in your router or open a port in order to play a game or use an application. To help you get a better connection for gaming or using an application, you can open a port in your CGM4231MDC and allow a direct connection.
In order to open ports in your Technicolor CGM4231MDC router, you need to:
- Go ahead and set up a static IP address on the computer or device that you are forwarding these ports to.
- Go ahead and log in to your Technicolor CGM4231MDC router.
- Make your way to the Port Forwarding section of the Technicolor CGM4231MDC router.
- Click on the Port Forwarding link at the left of the screen.
- Go ahead and create a Port Forwarding entry.
If this sounds difficult, you are not alone. We will walk you through each step in opening a port for the Technicolor CGM4231MDC router.
Step 1 - Setup A Static IP Address
It is important to set up 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.
Step 2 - Login To Your Technicolor Router
Log in to your Technicolor CGM4231MDC router. To log in you will need to use a web browser since the Technicolor CGM4231MDC uses a web interface to access router configurations.
Open up whichever internet browser that you are comfortable with. If you are not sure which one to use, then go ahead and open Chrome, Firefox, or Edge.

Once you have opened a web browser, find the address bar which is usually located at the top of the screen. The image below shows an example of this.

Once you have entered your router's IP address in the address bar go ahead and click the enter button on your keyboard. You should see a box like the one shown below.
Go ahead and enter the username and password for the Technicolor CGM4231MDC router in the spaces available. Remember if you have changed them in the past, you need to enter those values.
- The default Technicolor CGM4231MDC Router Username is: provided by ISP
- The default Technicolor CGM4231MDC Router Password is: provided by ISP
Enter your username and password, and then click the Login button to log in to your Technicolor CGM4231MDC router.
Technicolor Usernames and Passwords
If the username or password did not work check out our Default Technicolor Router Passwords page.
If you are unable to log in even after trying the above list of passwords you may need to consider a reset for your router. Our guide How to Reset a Router can help you with that. After resetting the Technicolor CGM4231MDC router your username and password will be reverted back to factory defaults.
Step 3 - Find The Port Forwarding Section
After a successful login to the Technicolor CGM4231MDC router you should be on the home page of your router. Now you need to find the Port Forwarding section.
- Click the Port Forwarding link at the left of the screen.
You are now on the Port Forwarding page.
Step 4 - Create A Port Forward Entry
Opening a port to a specific device may solve problems that you are having on your network. Make sure that it is necessary though, before opening a port, because you are effectively creating a pinhole in the firewall portion of your router that could lead to malicious traffic on your network. The risk is exceedingly low, though, so don't let this warning stop you from making this change if you need it.
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:
Click on the button that says Add Port Forward.
Enter the IP address that you are forwarding ports to into the Enter IP Address box. It is possible to forward a port to the IP address of your computer or to the IP address of a specific device on your internal network. Alternatively, select the device from the list.
Put a name for this forward in the Application box so that you can remember why you set this forward up. The name does not matter, so pick something that has meaning to you.
In the Protocols section, select the protocol type of the ports you are forwarding.
Enter the port number into the Start Port and the End Port boxes to forward a single port. If you are forwarding a range of ports, enter the lowest number of that range into the Start Port box and then enter the highest number of that range into the End Port box.
Enter the same values into the Target Port box that you entered into the Start Port box.
To finish adding an entry, click the button labeled OK.
Click the Save button at the top of the page when you are completely finished to apply these changes.
