Introducing Zero Trust Private Networking

What this post added

This post introduces Zero Trust Private Networking, enabling identity-aware network policies for traffic within private networks. It details the deprecation of the castle-and-moat model and the limitations of traditional VPNs. The solution involves using `cloudflared` to create secure TCP tunnels to Cloudflare's edge and WARP clients for user traffic. Network-based policies are enforced at Layer 4, allowing matching based on source/destination IP/port, and can be combined with identity policies for granular access control to private resources.
