Your Calix 813G-2 router has a firewall. A firewall is used to help protect your home network from unwanted Internet access. The firewall blocks all but a few specific ports. If you play an online game or use an online program, you may need to open additional ports so the game or program runs as it is suppose to. Opening ports is typically called a port forward.

In this guide we show you how to port forward on the Calix 813G-2 router. We will walk you through each of the following steps in detail:

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!

Step 1

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.

This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

NordVPN birthday deal!

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

Step 2

Now that the device you are forwarding the ports to has a static IP address, you need to login to the Calix 813G-2 interface. To do this you need to use a web browser. It doesn't matter which browser you decide to use. We recommend picking one you are familiar with. Some of the more common options are: Internet Explorer, Chrome, Edge, or Firefox.

After opening the desired web browser, find the address bar. You should be able to find this at the top of the page like:

Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.

The default Calix 813G-2 IP Address is:

If you have changed the router IP address in the past or you don't remember what you changed it to, then in order to find it you need to follow the directions on this How To Find Your Router's IP Address page.

After typing the router's IP address into the address bar, click the Enter key on your keyboard. You should get a Login page. It may look something like this:

Go ahead and enter the username and password for the Calix 813G-2 router interface. Then press the OK or Login button.

Note: The router username and password are NOT the same as the WiFi username and password.

Having Trouble?

This is a very common place to get stuck. If you find yourself needing help logging in, here are three things you can try:

  • The first thing you should try is other Calix usernames/password combinations. If you have a different firmware version you may also have a different username and password. Here is our list of Default Calix Router Passwords.
  • Next, it may be that you changed the password in the past and don't remember what you changed it to. We recommend trying to guess what you changed it to. For a guessing boost use our Find Password App. It is extremely handy and it guesses thousands of different passwords for you. Learn all about it on this Router Password Cracker.
  • Finally, after you have thoroughly exhausted your other troubleshooting options, you may need to do a factory reset on the device. Don't take this step lightly. A factory reset is a big step. All your personal configurations are lost and reverted to default. Learn the basics of a router reset on this How to Reset a Router page.

Step 3

This step is how to find the port forwarding section of the Calix 813G-2 interface. To help you out, we begin on the Home page.

Be sure that there is a dot in the Local Port and IP IP Address radio button.

Put a dot into the Remote Port and IP All IP Addresses radio button.

Enter the IP address to forward these ports to into the IP Address box. If you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box.

From the Protocol box select the protocol for the ports that you want to forward.

If you are forwarding a single port, enter that port number into the Local Port and IP Port Start, Local Port and IP Port End, Remote Port and IP Port Start and Remote Port and IP Port End boxes. If you are forwarding a range of ports, enter the lowest number of the range into the Local Port and IP Port Start and Remote Port and IP Port Start boxes. Then enter the highest number of the range into the Local Port and IP Port End and Remote Port and IP Port End boxes.

After you are done click the Apply button.

After each entry is completed you need to click the Apply button to save the port forward.

How to Tell if the Ports Forwarded.

So you typed everything in that you were suppose to... there are no neon lights to tell you all that work wasn't wasted. How do you tell if the ports actually forwarded?

To find out if your port opened correctly you need to use an Open Port Checker. We (of course) recommend using our Open Port Checker. Most online port checkers assume that you already have an application (such as your game or torrent) listening for the port test on your computer, and then assume that the test was OK simply because they were able to connect to your computer. Our port checker does not do this. We use a local application to see if the ports are open. With our open port check tool you never get a false positive.

Anything Else?

If the port forward did not go through or you are simply too confused, we recommend using our awesome Port Forwarding Software. Everyday we help hundreds of people get their ports open. Port forwarding should be easy. Our software provides you with everything you need to easily troubleshoot and fix your port forwarding issues.

Here at we have a lot of different guides to choose from. Do you need a game walkthrough? Do you need to learn how to port forward behind two routers? We have these and much more in our guide section.
