Deploying Gateway using a Raspberry Pi, DNS over HTTPS and Pi-hole

In this blog post, Jason Farber discusses how to deploy Cloudflare Gateway from home for protection against malware, phishing, ransomware and other security threats. He explains the concept of DNS filtering and its implementation using various methods such as DNS over HTTPS (DoH) with a Raspberry Pi, Pi-hole and DNSCrypt. Farber also provides detailed instructions on how to enable DoH in different browsers like Chrome, Firefox, Opera, etc., and configure Gateway for an entire home or business network using a Raspberry Pi as the DNS and DHCP server. The post concludes with a discussion on IPv4 check and lookup based on source IPv4 address and lookup based on IPv6 destination address as alternative methods to match requests in Gateway.
