Understanding the True-Client-IP Header
Connections from Cloudflare to origin servers come from Cloudflare IPs. 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.
For more details on what True-Client-IP is, refer to HTTP request headers.
To add the True-Client-IP
header to incoming requests, enable the Add “True-Client-IP” header Managed Transform.
