    I have a dedicated server (OVH) with Ubuntu 20.04 running a website via NGINX and a service using TCP/IP protocol on a specific port. There have been situations in the past where I have identified high bandwidth consumption coming from certain IPs/hosts, basically an attempted DDOS attack, which was interrupted by blocking the addresses/ASN. I would like to automate, if possible, this checking of IPs with high bandwidth consumption and block them automatically. Maybe implement some system to avoid other possible network problems as well.

    Hello. I am looking for someone who can help me setting up the following and finding a solution for the following: - Making the correct settings in cloudflare, so there is no bypass possible to leak the origin IP in any way. - Double Checking if the webserver IP is 100% hidden - (Setting up a VPS to use it as a webserver) The most important is that the origin IP has to be hidden behind cloudflare. Which it normally is but I was reading that there are ways to find out the origin IP if you have the wrong settings or other things went wrong. Thanks
