In this article, we will explain how to use RaspberryPi, as a Network Security Appliance for private network, which could be used to block all ADS, and secure the network by whitelisting/blacklisting DNS names.
It could effectively improve the overall network performance as all the AD requests going out of your private network will get blocked, and never goes out of your private network. It extends the protection to all computers in your network including mobile/other devices connects to your home network.
The below configuration shows, Pi-Hole deployed in Docker containers hosted on a RaspberryPi, and managed through Portainer (A Container orchestration platform, again running inside a Docker Container)
You could find the instructions on setting up the same here.
The only change we’d, is using a new version of Pi-Hole image (pihole/pihole:v5.0-armhf)
A single day operation statistics is given below: In a single day operation, Pi-Hole has blocked 31.7% of total requests, which are of type Ads.
Since the CPU/Memory (~4.5MB) footprints are pretty low, Pi runs smooth 24x7 and meets the network performance.
