It's hard to imagine any site that didn't use some sort of CDN. My wordpress wordfence plugin has been banning cloudflare ips instead of the real ip trying to bruteforce. I would be nice if we could enable that. I tried to search aptitude for a package that would enable it but I could not find one.
There should be no need for that module when using wordfence, check wordfence settings, there must be an option to enable to use the Cloudflare “CF-Connecting-IP” HTTP header to get a visitor IP.
