I have installed Fail2ban on my Ubuntu VPS. After I added nginx-noscript and nginx-404 configuration filters to fail2ban, cloudflare’s following IP address keep blocking.
I already added “real_ip_header CF-Connecting-IP;” to nginx file and looks like visitors IP addresses are properly restored (because my PC IP properly visible in access log). What could be the reason for this?
When I’m checking the who’s details for above IP’s it shows they belongs to Cloudflare.
Are there any solution? Or someone abusing my VPS?
Thank in advance.
