How Do I Make a FortiGate DNS Server?


Heather Bennett

Are you looking to set up a FortiGate DNS server? Look no further! In this tutorial, we will guide you through the process of creating your very own DNS server using FortiGate, a powerful network security appliance.

What is a DNS Server?

A DNS (Domain Name System) server is responsible for translating domain names into IP addresses. It acts as a directory for the internet, allowing users to access websites by typing in human-readable domain names instead of complex numerical IP addresses.

Why Use FortiGate as a DNS Server?

FortiGate is not only renowned for its robust security features but also offers comprehensive networking capabilities. By leveraging the power of FortiGate, you can easily create and manage your own DNS server within your network infrastructure.

Step 1: Accessing the FortiGate Web Interface

To begin, make sure you have access to the FortiGate web interface. Open your preferred web browser and enter the IP address of your FortiGate appliance in the address bar. Log in using your administrator credentials to access the management console.

Step 2: Configuring DNS Settings

Navigate to the DNS section within the FortiGate web interface. Here, you can configure various settings related to DNS functionality.

Setting Up Forwarders

If you want your DNS server to resolve external domain names, you need to set up DNS forwarders. These forwarders are responsible for forwarding requests for external domains to other DNS servers that can resolve them.

  1. In the DNS Forwarding Servers section, click on Add to add a new forwarder.
  2. Enter the IP address of the DNS server you want to use as a forwarder.
  3. Click on OK to save the configuration.

Creating DNS Zones

To create your own DNS zones and manage DNS records for your local network, follow these steps:

  1. Navigate to the DNS Zones section within the FortiGate web interface.
  2. Click on Add to create a new zone.
  3. Enter the name of your zone and select its type (e.g., Forward Zone or Reverse Zone).
  4. Add appropriate DNS records for your zone by clicking on Add.
  5. Save the configuration.

Step 3: Testing Your FortiGate DNS Server

To ensure that your FortiGate DNS server is functioning correctly, perform some tests:

  • Ping Test: Open a command prompt and ping one of your local domain names. If it resolves to the correct IP address, it means your FortiGate DNS server is working properly.
  • Dig Test: Use the dig command-line tool or other similar tools to query your FortiGate DNS server for specific domain records. Verify that it returns accurate results.

You have now successfully set up a FortiGate DNS server! Enjoy the benefits of having your own internal DNS infrastructure that provides enhanced security and control over domain name resolution within your network.

Note: It’s important to regularly monitor and maintain your DNS server to ensure optimal performance and security. Keep an eye on updates and patches released by Fortinet to address any vulnerabilities.

Happy DNS server administration!
