Cisco M20 routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.
The basic process to open a port is:
- Setup a static IP address on either your computer or device that you want to forward a port to.
- Login to your Cisco M20 router.
- Navigate to the port forwarding section.
- Click the Applications & Gaming link.
- Click the Port Range Forwarding or the Single Port Forwarding button to forward ports.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Cisco M20 router.
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.
- Recommended - Our free program will setup a static IP address for you. Download Network Utilities today!
- Another highly recommended way of getting a permanent IP address is to set up a DHCP Reservation.
- Or, follow our Static IP Address Setup guides.
With DHCP reservations you can manage your devices from your router. This centralizes the management of your network and helps prevent IP address conflicts. Using this method you do not have to log in to your devices separately.
Now we are going to login to your Cisco M20 router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.
Open up your web browser and find the address bar. It should look something like this:
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 Cisco M20 IP Address is: 192.168.1.1
After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:
You should see a box prompting you for your username and password.
- The Default Cisco M20 Router Username is: admin
- The Default Cisco M20 Router Password is: blank
Enter your username and password, and then click the Login button to log in to your Cisco M20 router.

If your username and password do not work then please visit our Default Cisco Router Passwords page.
If you still can't login to your router because you forgot your Cisco M20 router username and password, use our How to Reset a Router Password guide to set your Cisco M20 router back to its factory settings.
Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the first page in your router:
Click the Applications & Gaming link near the top of the page.
This router has two different sections that allow you to forward ports. One section allows you to forward a range of ports, and the other allows you to forward a single port. To forward a range of ports, click Port Range Forwarding. To forward a single port, click Single Port Forwarding.
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:
Forwarding a Single Port
Put a name for this forward in the Application 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.
Enter the same port number to be forwarded into both the External Port and the Internal Port boxes.
From the Protocol box select the protocol for the ports that you want to forward.
You need to enter the IP address that you are forwarding ports to in the To IP IP Address box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.
Make sure that the Enabled checkbox is checked.
Forwarding a Port Range
Enter the name of the program into the Application Name box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded is be a good idea.
If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Start Port box and the highest number of that range into the End Port box. If you are only forwarding a single port number then enter that number into both the Start Port and the End Port boxes.
Use the Protocol dropdown box to select the protocol type of the ports you are forwarding.
You need to enter the IP address that you are forwarding ports to in the To IP Address box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.
Verify that you have the Enabled checkbox checked.
When you're finished, click Save Settings near the bottom of the screen to save your changes.
Test if Your Ports are Open
Now that you have forwarded ports on the Cisco M20 you should test to see if your ports are forwarded correctly.
To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Check tool is the only online port checking tool with Guaranteed Results.
