Logging Client IP in Apache Behind CloudFlare

Note: This article only covers Acquia’s non-Kubernetes version of Acquia Cloud infrastructure, referred to as Cloud Classic.

This feature is currently unavailable for the Acquia Cloud infrastructure, previously referred to as Cloud Next.

Issue

Since CloudFlare, Acquia Cloud Edge Protect, and Acquia Cloud Edge CDN act as a reverse proxy, the IP address in Apache logs will show the CloudFlare IP address instead of the visitor's true IP address.

Resolution

To restore the true IP address of the visitor, please submit a Support ticket to request a reverse proxy header to CF-Connecting-IP.
