Cloudflare Restoring Visitor IP in Ubuntu Plesk Apache Server

When using Cloudflare CDN, visitors come to the Cloudflare server and Cloudflare fetches pages from your server and sent to the visitor. Your server only sees Cloudflare’s IP address. To fix this, we can use the Apache module remoteip.

On Ubuntu (or Debian) server running Plesk control panel with Apache webserver (no Nginx) do the following to restore real visitor IP address when using Cloudflare CDN.

Enable mod_remoteip

a2enmod remoteip

Create file

vi /etc/apache2/conf-enabled/remoteip.conf

Add the following to the file

RemoteIPHeader CF-Connecting-IP
RemoteIPTrustedProxy 173.245.48.0/20
RemoteIPTrustedProxy 103.21.244.0/22
RemoteIPTrustedProxy 103.22.200.0/22
