Question
Best way to configure Load Balancer with Cloudflare
- Posted June 11, 2021
- DigitalOcean Managed Load BalancersApache
I need to integrate Cloudflare with my droplets through the Managed Load Balancer provided by DigitalOcean.
This is my current configuration:
Cloudflare
- WAF Configured
- Proxy Navigation Enabled (To support WAF)
- Use of SSL provided by Cloudflare
- IPv6 Enabled
DigitalOcean
- Two Droplets with Apache
- HTTP2 Enabled
- IPv6 Enabled
- SSL/HTTPS configured with my own security certificate from my domain
- Cloud Firewall rules that only allow access on port 80 and 443 by the DO balancer
How should I configure the DigitalOcean load balancer to support this integration, and keep the original IP of the client coming from Cloudflare?

Hi there,
The setup looks very good. The DigitalOcean Load Balancers will set some HTTP headers that pass the source IP through to your backend servers, like Cloudflare does with
X-Forwarded-For, andCF-Connecting-IPheaders.From the Protocol Support section of the docs:
Hope that this helps! Regards, Bobby
