Can a Cloudflare tunnel block unwanted access? r/selfhosted Jul 1, 2026 · 11d ago
A home-hosted app is being exposed through a Cloudflare Zero Trust Tunnel multi-factor authentication
The main question is whether this setup can stop all unauthorized access to the exposed app. VPN or Tailscale is understood to be better, but those options are not available in this case.
Radar's take This matters for anyone running a Mac mini server
The practical caution is that “all unauthorized access” is a high bar. The setup is only as strong as the access policy, account security, tunnel configuration
Key points The app would be exposed through a Cloudflare Zero Trust Tunnel Cloudflare login would be the only access method. Only one account would be allowed to sign in. Multi-factor authentication VPN or Tailscale is considered better, but unavailable
