DNS-Over-TLS Built-In & Enforced - 1.1.1.1 and the GL.iNet GL-AR750S

This post details the integration of Cloudflare's 1.1.1.1 resolver with DNS-Over-TLS (DoT) support in the GL.iNet GL-AR750S router. It highlights the router's UI options for enabling DoT and enforcing encrypted DNS traffic for all clients. The post also includes technical details on how to verify encrypted DNS traffic using tcpdump and references previous work on configuring DoT on OpenWRT routers. The core contribution is the demonstration of a partner product natively supporting and enforcing DoT with Cloudflare's DNS service.
