About Cloudflare Tunnel
cloudflared runs on the machine hosting your service and makes an outbound connection to Cloudflare's network. Requests then arrive through that connection rather than through an inbound port, so your firewall can stay completely closed and your origin's real address is never exposed.
That makes it a common way to publish something running at home or behind carrier-grade NAT where port forwarding is impossible. The same tool also handles Layer 4 traffic such as SSH and RDP through `cloudflared access`, and Cloudflare's WARP client can reach tunnelled origins without needing cloudflared on the client side.
You need a Cloudflare account, and for historical reasons a domain on Cloudflare, even though private routing can technically work without a site.
Strengths
- No inbound ports opened; the daemon connects outbound to Cloudflare
- Works behind carrier-grade NAT where port forwarding is impossible
- Your origin's real IP address is never exposed
- Handles SSH and RDP as well as HTTP through cloudflared access
Limitations
- Requires a Cloudflare account and a domain on Cloudflare
- Your traffic passes through Cloudflare, which is a dependency and a trust decision
- Zero Trust access policies beyond the free tier are paid
- If Cloudflare has an outage, your tunnelled service is unreachable
