Restoring original visitor IP for cPanel Apache under CloudFlare

Please note that installing mod_cloudflare is not working anymore at least since January 2021.

Instead you need tp install mod_remoteip.

It can be done via:

1. Yum installer with command: yum install ea-apache24-mod_remoteip

or

2. Using WHM -> EasyApache 4 -> Customize -> Apache Modules, search for remoteip.

After install remoteip module you need to find the file:

/etc/apache2/conf.modules.d/NNN_mod_remoteip.conf
where NNN is a sequence of digits, it can be different or different hosts.

Note: on CentOS 6 it can be found at /etc/httpd/ directory.

Edit the file and add the following content to it's bottom:
