How Cloudflare Works

Cloudflare acts as a reverse proxy, protecting and accelerating your web applications.

Non-Proxy (DNS Only)
With Proxy
Cloudflare Tunnel

Non-Proxy (DNS Only)

In this mode, Cloudflare only handles DNS resolution. Users connect directly to your server without any protection or optimization.

User

Makes DNS query

DNS Server

Returns server IP

Web Server

Returns content directly

Note: No protection & optimization on your website. Attackers will reach your origin server directly.

With Proxy

When proxy is enabled, Cloudflare sits between users and your server, providing security, performance, and reliability.

User

Requests content from Cloudflare IP

Cloudflare

Blocks threats & optimizes content

Web Server

Returns content to Cloudflare

Benefits: CDN, WAF, DDoS Protection, optimization, etc. Attacks are blocked at Cloudflare's network.
Note: Attacks are still possible with the knowledge of server IP address (bypass Cloudflare). Non-HTTP traffic not allowed.

Cloudflare Tunnel

Cloudflare Tunnel creates a secure, encrypted connection between Cloudflare and your server without exposing your public IP.

User

Requests content from Cloudflare IP

Cloudflare

Blocks threats & optimizes content

Cloudflared

Secure tunnel to server

Web Server

Returns content via tunnel

Benefits: Blocks all inbound port 80 & 443 to server. Attackers can't directly attack the server IP address.

SSL Connections

Understanding how SSL certificates work with Cloudflare's proxy service.

User

Cloudflare SSL Certificate

Cloudflare

Server SSL Certificate

Web Server

Question 1: How many SSL certificates are needed based on the diagram?

Question 2: How many SSL (HTTPS) connections are needed to establish a full secure connection?

Note: ROS decided to use their own custom SSL certificate purchased from GlobalSign, SSLCorporation and upload it to the Cloudflare network, so all users will still see the GlobalSign and SSLCorporation certificate even if the traffic is now served by Cloudflare.
