Your CGM4140COM router helps to protect your network by blocking incoming internet connections. This is an important feature that helps you to control which applications have access to your network. Sometimes you want to allow network access to a specific application in order to play a game, connect a device, or use an app. The Technicolor CGM4140COM can unblock certain incoming connections through port forwarding or by opening a port. You can open ports in your CGM4140COM by assigning specific ports to an IP address. Forwarding these ports directs incoming data to a specific device or application.

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 CGM4140COM router your username and password will be reverted back to factory defaults.
Step 3 - Find The Port Forwarding Section
You should be on the home page of your Technicolor CGM4140COM router once you have successfully logged in. Find the Port Forwarding section of your router.
- Click on the Advanced tab at the left of the screen.
- Click the Port Forwarding link at the left of the screen.
You should now be on a page called Port Forwarding.
Step 4 - Create A Port Forward Entry
Make sure that you must open a port in your router before doing so since this will allow data to come through the firewall portion of your router to a specific device. It is possible that this could lead to malicious traffic on your network. However, don't let this warning stop you from making this change if you need it because the risk is very low.

- Click on the Add Service button.
- Make the Other selection in the Common Service drop-down list.
- Put a name for this forward in the Service Name 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.
- Choose TCP/UDP from the Service Type drop-down list.
- Enter the IP address that you are forwarding ports to into the Server IPv4 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.
- Leave Server IPv6 Address blank.
- Go ahead and enter the port number into the Start Port and the End Port boxes, to forward a single port. To forward 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.
- Make sure to click the Save button at the bottom of the page to apply these changes, when you are completely finished.
