Opening ports on your home router is a security nightmare. Cloudflare Tunnel creates an encrypted outbound connection from your server to Cloudflare's edge — no open inbound ports required.
Configure multiple self-hosted services behind a single tunnel with Cloudflare Access policies for zero-trust authentication.
| Attack Vector | Port Forwarding | Cloudflare Tunnel |
|---|---|---|
| Port scanning | Vulnerable | Impossible |
| DDoS | Direct hit | Absorbed at edge |
| Zero-day | Exposed | Cannot reach origin |
| IP leak | Visible | Hidden |
