A Cradlepoint MBR1200B router contains a basic firewall to help protect your home network. A Firewall blocks incoming connections by nature. Sometimes you need to unblock some of these connections so you can run a game or application. This is called opening a port or port forwarding. Port forwarding is literally forwarding a port from the internet to your home network.

You need to follow the steps below to open ports in your Cradlepoint MBR1200B router:

  1. Set up a static IP address on the computer or device that you are forwarding ports to.
  2. Log in to your Cradlepoint MBR1200B router.
  3. Make your way to the Port Forwarding section of the Cradlepoint MBR1200B router.
    • Click the Security tab, which is at the left of the screen.
    • Click the Zone Firewall link, which is at the left of the screen.
    • Click on the Port Forwarding link at the left of the screen.
  4. Create a Port Forwarding entry.

Step 1

It is important to set up a static IP address in the device that you are forwarding a port to. This ensures that your ports remain forwarded even after a reboot, power outage, or another type of device or router disconnect.

After setting up a static ip address on your devices you need to login to your router.

Step 2

The Cradlepoint MBR1200B router uses a web interface to display router settings. In order to login to the Cradlepoint MBR1200B router you need to use a web browser.

Open your favorite web browser. If you don't have a favorite or are not sure what this means, open up Chrome, Firefox, or Edge. If you are already in a browser window, go ahead and open up a new tab.

We have simplified this step for you with this link: Login to your MBR1200B Router

Find the address bar in your browser window. This is usually found at the top of the page, like in the image below.

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

The Cradlepoint MBR1200B router's default IP address is:

Enter your router's IP address into the address bar of your browser and click the enter button on your keyboard. A box like the one below should appear.

This is the login page from your Cradlepoint router.

Go ahead and enter the username and password for the Cradlepoint MBR1200B router in the spaces available. Remember if you have changed them in the past, you need to enter those values.

Enter your username and password, and then click the Login button to log in to your Cradlepoint MBR1200B router.

Cradlepoint Username and Password Trouble

If the username and password that you typed in did not work, check out our Default Cradlepoint Router Passwords page for other ideas about possible passwords.

If, after trying the above list of passwords you still can't log in, you may need to reset your router. Learn how to do that by reading our How to Reset a Router guide. After resetting the Cradlepoint MBR1200B router your username and password are reverted back to factory defaults. Router settings may also change when you reset, so make a note of your current router settings before you reset.

Step 3

You should be on your routers home page once you complete logging in. Find the Port Forwarding section on the home page of the Cradlepoint MBR1200B router.

This is the home page from your Cradlepoint router.

You should now be on a page that says Port Forwarding.

Step 4

Opening a port to a specific device may solve problems that you are having on your network. Make sure that it is necessary though, before opening a port, because you are effectively creating a pinhole in the firewall portion of your router that could lead to malicious traffic on your network. The risk is exceedingly low, though, so don't let this warning stop you from making this change if you need it.
