How do I setup port forwarding?

If you have a Calix 844G optical network terminal (ONT), you can setup port forwarding yourself. If you use a third-party router to access the internet such as a Linksys or Belkin, you will need to refer to the manufacturer’s documentation regarding port forwarding.

Step 1
Identify that you have a Calix 844G ONT. It will be located in your utility room, often near your circuit breaker box or air handling equipment. It will look like the photo below.


Step 2
Find the information sticker on the front of the ONT. You’ll need the username and password from the ONT in order to access it.

Step 3
Using your web browser, navigate to the IP address of the ONT. It is recommended that you complete the following steps using a device with a larger screen.

Step 4
Enter the username and password from the information sticker and then click Login.

Step 5
Choose the Advanced option.

Step 6
From the menu on the left-side, choose Security, then choose Port Forwarding under that menu.

Step 7
The Port Forwarding screen will display any devices that currently have a port forwarding rule. To add a new port forwarding rule, choose New.

Step 8
This step assumes that you know the port and device that you wish to forward. Improper configuration on this step can render the ONT inoperable, causing you to lose your voice, video, and data services. It is important to double-check the settings.

You can either manually enter the IP of the device you wish to forward traffic to or you can select the device (if connected to your network) from the drop down.

Then, select the appropriate protocol followed by entering the Port Start (e.g. 8050) and Port End (e.g. 8051).

Finally, enter the remote ports. These are the ports that you would use to access the device remotely. For instance, if your IP address is and the device is listening on port 8050, you would use Port Start 8050 and Port End 8051 in the Remote Port and IP section. You could then type from your browser to access the device on your internal network.

Once you have verified your settings, choose Apply. The port forwarding rule will be saved and take effect immediately.
