Orange Cloud (Proxy)

Learning Focus

By the end of this lesson you will understand what happens when Cloudflare's proxy (orange cloud) is enabled for a DNS record.

What the Orange Cloud Does

When enabled, Cloudflare becomes a reverse proxy between visitors and your server:

Benefits of proxied mode:

  • CDN caching for static assets
  • DDoS protection at the edge
  • WAF rules applied before traffic reaches your server
  • Your origin server IP is hidden from the public
  • Free HTTPS on the Cloudflare edge

What Gets Proxied

ProtocolProxied?Notes
HTTP/HTTPS (80/443)✅ YesStandard web traffic
SSH (22)❌ NoUse DNS-only records
Email (25, 587, 993)❌ NoMust be DNS only
Custom TCP ports❌ No (without Spectrum)Cloudflare Spectrum needed

When to Disable Proxy (Grey Cloud)

  • Email servers (MX records)
  • SSH or SCP access records
  • Direct database connections
  • Services on non-standard ports
info

The orange cloud hides your server's real IP address. This is a security benefit — attackers cannot target your server directly.

Key Takeaways

  • Orange cloud (proxied) routes traffic through Cloudflare's CDN and security layer.
  • Only HTTP and HTTPS traffic is proxied by default.
  • Use DNS-only (grey cloud) for email, SSH, and non-HTTP services.

What's Next

  • Continue to Real Visitor IP for restoring real client IPs behind the proxy.
