How to set up Smart DNS on DD-WRT Routers

In this tutorial we will show you how to set up Smart DNS on DD-WRT Routers but first let’s see what are our requirements and recommendations.

Requirements

In order to set up the Smart DNS you will need:

  1. A CactusVPN account. If you don’t have one you can try our services for free.
  2. Your DNS addresses. You can find them in Settings -> DNS Servers in Your Account our website.

If you still want to set up Smart DNS manually, go step-by-step through following instructions:

Part I. Validate Your IP Address

If you have already validated your IP address go straight to the “Part II. Change your Windows DNS addresses” of this tutorial.

  1. Sign in to your account on our website and go to Settings -> Validate Your IP Address.
  2. Click on Validate IP button.

If you see the “Validated” green label near your IP address, go straight to the “Part II. Change your Windows DNS addresses” of this tutorial

Remember! You have to validate your IP address each time it changes. If your Smart DNS service is not working, just try to validate your IP address again.

You also have other two options to validate an IP address:

Part II. Change your router DNS addresses

This has to be done only once.

It is important to save your original DNS settings before making any changes. You might need them in case you will want to switch back to your original settings.
  1. Log in to your router, go to “Setup” tab (3), then choose “Basic Setup” (4).
