Cisco Linksys-E900 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 Linksys E900 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 Linksys-E900 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!
- Or, follow our Static IP Address Setup guides.
After setting up a static ip address on your devices you need to login to your router.
Now we are going to login to your Cisco Linksys-E900 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 Linksys E900 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 Linksys E900 Router Username is: admin
- The Default Cisco Linksys E900 Router Password is: blank
Enter your username and password, and then click the Login button to log in to your Cisco Linksys-E900 router.

If you still can't login to your router because you forgot your Cisco Linksys-E900 router username and password, use our How to Reset a Router Password guide to set your Cisco Linksys-E900 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
Create a name for this forward and put it in the Application Name box. The name is only used as a reminder and has no effect on the port forward.
Put the same port number into both the External Port and the Internal Port boxes.
Select the protocol type of the ports you are forwarding from the Protocol box.
Enter the IP address that you are forwarding ports to in the To IP IP Address box. This is either the IP address of a computer or the IP address of another device on your network.
Enable the Enabled checkbox by putting a check in it.
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.
Select the required protocol for these ports from the Protocol dropdown box.
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.
Make sure that the Enabled checkbox is 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 Linksys-E900 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.
