What is True Client IP?
If True Client IP is enabled, CloudFlare will add a header in the request sent to the origin with the IP address of the end user.
By default, CloudFlare sends back packets with a CloudFlare IP address. True Client IP is a solution that allows CloudFlare users to see the end user’s IP address, even when the traffic to the origin is sent directly from CloudFlare.
This feature supplements our current CF-Connecting-IP and X-Forwarded-For headers.
