How to Port Forward the Cisco EPC3925

Your Cisco EPC3925 includes a pretty basic firewall that helps protect your local network from unwanted Internet access. The firewall does this by actively blocking all incoming and outgoing Internet connections unless you specify otherwise. Some online games and applications work much better if additional connections are allowed through the firewall. In order to allow more connections through the firewall you need to create a port forward.

In this guide we will walk you through each of the steps involved in forwarding ports on the Cisco EPC3925 router. These steps include:

  1. Setting up a static IP address on device you plan on forwarding ports to.
  2. Logging into the Cisco EPC3925 router.
  3. Finding the port forwarding section in the router interface.
  4. Entering the port forward information on the port forwarding page.

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.

  • Recommended - Our free program will setup a static IP address for you.
    Download Network Utilities today!

  • Or follow our Static IP Address guide to setup a static IP address.

TIP: I recommend writing the Static IP address down, you need it in Step 4.

Step 2

It is time to login to the Cisco EPC3925 router. To login to the router you need to use a web browser. It should not matter what browser you decide to use, simply pick your favorite. Some common options are Chrome, Internet Explorer, and Firefox.

Open up the browser you picked and find the address bar. This should be at the top of the page like this:

In the above image the address bar has been circled and it has in it. Simply replace what is in the address bar with the Cisco EPC3925 IP address. This can be referred to as the router's IP address, router's GUI address, and the computer's default gateway.

The default IP address of the Cisco EPC3925 router is:

After entering the IP address into the address bar, click the Enter key. If everything went as it should have you will see an authentication window or box like this:

If you are not shown the above screen, something went wrong. At this point you need to find out what the router's IP address was changed to. In order to do this follow the instructions on our How To Find Your Router's IP Address page.

Your goal is to see a screen that prompts you for a username and password.

  • By default there is NO default username for the Cisco EPC3925 router.
  • By default there is NO default password for the Cisco EPC3925 router.

Of course if you have changed the username and password the above values will not work. Enter the username and password for your router and press the Log In button.

Cisco Usernames and Passwords

This is a very common place to get stuck. Here are a few things you can try:

  • We first recommend trying other Cisco username/password combinations. It is possible you have a different version than this. Different versions sometimes have different passwords. Here is our list of Default Cisco Router Passwords.

  • The most common reason a password won't work is because you have changed it in the past. You can do a couple things here: First, you can try guessing what you changed it to. Second you can use our Router Password Cracker to do the guessing for you. This handy tool really does make owning a router a lot easier.

  • The last thing you can try is a factory reset. Do not attempt a factory reset unless you have exhausted all your other troubleshooting options. To learn the basics of a reset read this How to Reset a Router page.
Step 3

Now that you are logged into the Cisco EPC3925 router it is time to find the port forwarding section. To help you with that we start on the Home page.

On this page click the Applications & Gaming option at the top of the page.

Under that there are more choices. Pick the one titled Port Range Forwarding.

You should now be on the correct page to make a port forward entry.

Step 4

It is now time to enter the port forwarding information into your router. To help you with this step we need a little more information from you:

Application :
IP Address :

(Enter the Static IP address you created in Step 1 into the IP address box.)

This next section we call the router simulator. It simulates the port forwarding page of the Cisco EPC3925 router. Right now we are showing you want to port forward XBox Live. If this is correct, go ahead and fill in the boxes in your router as you see them below.

When you are finished, click the Save Settings button at the bottom of the page.

Testing the Port Forward

In order to quickly find out if the port forward you just completed on the Cisco EPC3925 router went through correctly we recommend using a Open Port Checker. If you use our Network Utilities tool, it includes a free Open Port Checker. Our Open Port Checker is the only one online that has Guaranteed Results.

Wait, there's more...

If you are still having trouble with port forwarding, use our Port Forwarding Software. It is and easy and fast way to get your port forwarded.
