My website was under DDOS attack from specific IP address. I want to disable the requests from that IP to the domain including all the subdomains.
I tried blocking using IP Access Rules settings from Firewall > Tools but this block only requests to the main domain registered with the Cloudflare.
I have many subdomains configured through DNS but requests to the subdomains are working is not being blocked.
How can I block access to the domain including the subdomains?
