How to open a port on the Westell A90-750015-07

This Westell A90-750015-07 router includes a basic firewall that protects your home network from unwanted Internet access. Very basically the firewall works by blocking unauthorized connections to and from the Internet. Some online games and programs will run much smoother if you open additional connections. This process of opening more connections is called a port forward.

In this guide, I will show you how to port forward on the Westell A90-750015-07 router. The steps I will show you are:

  1. How to setup a static IP address on either your computer or device that you want to forward a port to.
  2. Login to your Westell A90-750015-07 router.
  3. Navigate to the port forwarding section.
  4. Create a port forward entry.

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.
