Advanced Pi-hole Configuration: Maximize Your Network Ad Blocker

If you’ve followed our basic Pi-hole setup guide, you already have an ad-free, secure network. But there’s much more that Pi-hole can do! In this advanced guide, we’ll show you how to unlock its full potential with custom block lists, DNS filtering, performance tweaks, and integration with other security tools.

Custom Block Lists

Pi-hole comes preloaded with a basic ad-blocking list, but you can significantly enhance its capabilities by adding custom block lists to filter specific content like malware, adult sites, or tracking domains.

How to Add Custom Block Lists:

• Access the Pi-hole admin interface: http://<pi-hole-ip>/admin
• Navigate to Adlists
• Add the URLs of your desired block lists. Here are some popular block lists: Ultimate Adlist (the one I use) (you will have to browse to find the adlist that fits your situation best, below is the ‘general use’ list) Basic Multi List Included
• Click Save and then update Pi-hole by running:

  pihole -g
  

Where to Find Block Lists:

• Popular sources for block lists include:
  • firebog.net
  • OISD
  • reddit can yield some good results as well

Network-Wide DNS Filtering

Pi-hole can be expanded into a network-wide DNS filtering solution, helping to block access to known malicious websites, phishing domains, and unwanted content across all devices on your network.

Set Up DNS Filtering:

• Edit the DHCP configuration for your network (usually it’s your ‘wireless router’ that functions as a DHCP server) You will simply add the IP of your pi-hole installation to the first DNS entry. You’ll have to wait for the lease time to expire, this can vary between networks.

Optimizing Pi-hole Performance

To ensure Pi-hole runs efficiently, especially on larger networks or Raspberry Pi setups, consider the following optimizations:

Hardware Optimization:

• For high-traffic networks, consider upgrading to a more powerful device, such as a Raspberry Pi 4 or a dedicated mini-server.
• Reduce logging frequency for a smoother experience on lower-power devices (reduces DNS log storage to 24 hours):

  pihole -l 24h
  

Caching DNS Queries:

• Enable DNS caching to reduce latency on frequently visited websites. This can be done by adjusting the cache-size in the Pi-hole settings.

Whitelisting Critical Domains:

• Some services (e.g., banking, streaming) may experience issues with aggressive blocking. You can whitelist critical domains through the admin interface: Go to Domains Add any domains that should bypass blocking and click ‘Add to Whitelist’.

Conclusion

With these advanced configurations, your Pi-hole setup can evolve from a simple ad blocker to a comprehensive network security tool. Whether you’re optimizing for performance, expanding your filtering capabilities, or integrating with other security tools, Pi-hole offers immense flexibility.
