Welcome back to Dev Odyssey Home Networking! In this video, I teach you how to secure your home network, by using a DNS Sinkhole called Pi-hole!

It's main purpose is to block websites that are undesirable and dangerous. This includes, malicious and phishing websites, ads, and more.

With this protection in place, you better protect your home network, computers and devices from going to bad websites, and potentially letting malicious actors into your home network.

This is by far one of the best solutions you can use to protect your data, secure your network, and make the internet safer to surf.

Description / Outline

1. Flash Raspbian (Lite or desktop) onto an SD card using Balena etcher (or could use raspberry imager).
1. Open boot partition and add an empty SSH file. If connecting over WiFi, add wpa_supplicant.conf file to connect to WiFi on boot. Power on / connect networking
2. Log in with SSH (pi username, raspberry password)
3. Run sudo rasp-config, change password, change hostname, expand file system, reboot
2. Install Pi-hole (using script from GitHub, follow all defaults for this installation)
3. Set Pi-hole IP Address as Static IP (manually or via router)
4. Configure Pi-hole (add block lists of malicious / phishing domains and test out blocking)
5. Set up router DNS as Pi-hole / hand out Pi-hole as DNS
6. Bonus: Prevent external DNS servers from being used / manually configured on devices using firewall rules (only allow Pi-hole server to make outbound DNS requests)
1. Rule to allow Pi-hole out on UDP port 53 to Cloudflare DNS
2. Rule to block all clients, UDP port 53 to external zone
