Using SonicWall as a DNS Server

Are you looking to configure SonicWall as a DNS server? In this tutorial, we will walk you through the steps to set up and manage SonicWall as your DNS server. So, let’s get started!

Step 1: Accessing the SonicWall Management Interface

To begin, open your preferred web browser and enter the IP address of your SonicWall device in the address bar. Press Enter to access the management interface.

If you don’t know the IP address of your SonicWall device, you can find it by using tools like Angry IP Scanner or checking your network settings.

Step 2: Logging in to the Management Interface

Once you have accessed the management interface, enter your admin username and password to log in. If you haven’t changed these credentials before, try using the default username “admin” and password “password.” It is recommended to change these default credentials for security reasons.

Step 3: Configuring DNS Settings

After logging in, navigate to the “Network” section or “DNS” settings tab. Here, you will find options to configure various DNS-related settings.

Primary DNS Server

To set up SonicWall as your primary DNS server, enter the desired IP address in the designated field. Make sure that this IP address corresponds to a valid DNS server that you want to use for name resolution.

Note: Ensure that there are no typographical errors while entering the IP address.

Secondary DNS Server

If you want to configure a secondary DNS server for redundancy, enter its IP address in this field. This secondary server will be used if the primary server is unavailable or experiencing issues.

  • TIP: It’s good practice to use multiple DNS servers for better reliability and load balancing.
  • IMPORTANT: Ensure that the secondary DNS server is a different device with a unique IP address.

DNS Forwarding

In some cases, you may want SonicWall to forward DNS queries to another DNS server instead of directly resolving them. To enable this feature, enter the IP address of the server you want to forward queries to.

Note: This can be useful when you want SonicWall to act as a proxy for DNS requests.

Step 4: Applying Changes and Testing

Once you have configured the necessary DNS settings, don’t forget to click on the “Apply” or “Save” button to save your changes.

To ensure that SonicWall is functioning correctly as a DNS server, perform some tests. You can use tools like nslookup or ping from a client device connected to your network. Verify if the DNS resolution is working as expected.


Congratulations! You have successfully configured SonicWall as your DNS server. By following these steps, you can now leverage SonicWall’s capabilities for efficient name resolution within your network.

Remember, managing and maintaining a reliable DNS infrastructure is crucial for smooth network operations. With SonicWall as your DNS server, you can enhance security and optimize performance.
