Everything you wanted to know about using Cloudflare Zero Trust Argo tunnels for your personal network. For those like me who were still confused even after reading the article, I think this is the lowdown:

• ZT tunnels let you expose private resources/services to the internet (or your users) via Cloudflare’s edge network. You install cloudflared on an internal host, and register a “tunnel” so that requests to a hostname or IP get forwarded securely into your network (similar to tailscale).
• Unlike classic VPNs (which open full network access) or traditional Cloudflare tunnels (which merely publish a service), this approach adds granular access control; you can define exactly who can access which resource, based on identity, device posture, login method, etc.
• It also solves NAT/firewall issues often faced by P2P-based overlays (e.g., Tailscale) by routing everything through Cloudflare’s network, avoiding connectivity failures when peer-to-peer fails.

For in-browser auth you can then use Cloudflare Access, or you can install the cloudflare Warp client which is a VPN-like thing that would give you full control over the access to whatever service(s) you were exposing this way.
