CloudFlare Proxy address blocked after implementing IPBAN?
Hi, yesterday we implemented IPBAN (https://github.com/DigitalRuby/IPBan/) on some of our Windows servers to automatically block dodgy IPs from hitting our servers. Today, some of our customers were complaining that they couldn't access their portal, served by IIS. When we turned off the firewall rules created by IPBAN, customers could immediately access their portals again.
The only thing I can imagine is that somehow a CloudFlare proxy address was blocked? But none of the addresses recored by IPBAN, correspond to the addresses listed on the CloudFlare IP page (https://www.cloudflare.com/ips/).
Does anyone have any advice on where we can look to narrow down the cause of the problem?
Thanks
