How to Add Host Overrides to pfSense DNS Resolver

As a hobbyist network administrator, I’ve always been a bit of a perfectionist when it comes to my home network setup. One of the things that has been driving me crazy lately is the inconsistent DNS resolution on my pfSense router. Some devices would resolve hostnames just fine, while others would fail to connect to the internet altogether. After doing some troubleshooting, I realized that the issue was with the DNS resolver on pfSense.

pfSense is a popular open-source firewall and router distribution that is based on FreeBSD. It is known for its reliability and flexibility, but the default DNS resolver can sometimes be a bit buggy. One of the ways to fix this is to add host overrides to the DNS resolver. This allows you to manually specify the IP address for a particular hostname, which can be useful for resolving issues with inconsistent DNS resolution.

What is a Host Override?

A host override is a way to manually specify the IP address for a particular hostname. This can be useful for a number of reasons, such as:

• Resolving issues with inconsistent DNS resolution
• Speeding up DNS resolution for frequently accessed websites
• Blocking access to specific websites

How to Add a Host Override to pfSense

Adding a host override to pfSense is a relatively simple process. Here are the steps:

1. Log in to the pfSense web interface.
2. Navigate to Services > DNS Resolver.
3. Click on the “Host Overrides” tab.
4. Click on the “Add” button.
5. Enter the following information:
• Hostname: The hostname that you want to override.
• IP Address: The IP address that you want to associate with the hostname.
• Description: A description of the host override.
6. Click on the “Save” button.

Tips for Using Host Overrides

Here are a few tips for using host overrides:

• Only create host overrides for hostnames that you need to override. Creating too many host overrides can slow down DNS resolution.
• Use host overrides to speed up DNS resolution for frequently accessed websites. This can be especially useful for websites that are hosted on a slow or unreliable server.
• Use host overrides to block access to specific websites. This can be useful for blocking websites that contain malware or other harmful content.

Conclusion

Host overrides are a powerful tool that can be used to improve the performance and security of your pfSense router. By following the steps in this article, you can easily add host overrides to your pfSense router and start enjoying the benefits.
