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.

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 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:

Validate a specific IP address

Validate IP using a web address

Part II. Change your router DNS addresses

This has to be done only once.

1. Log in to your router, go to “Setup” tab (3), then choose “Basic Setup” (4).
   
   

   

2. Enter CactusVPN DNS Server (5). You can find them in Settings -> DNS Servers in Your Account on our website.
3. After that check the checkbox next to “Use DNSMasq for DNS” (6).
   
   

   

4. Click on the “Apply Settings” button (7). This will reboot your router and will apply new DNS servers.
   
   

   

That’s all!
