How to Block A specific IP address?

Hi - I need to block a set of IP addresses with hacker activity. When I entered a firewall rule for “IP Source Address”, the IP address still reached my site and attempted to log in. What is the best way to block an IP address from reaching my site?

You first need to make sure your server is blocking access for any IP address that’s not on the list at

Once you can stop them from bypassing Cloudflare, a Firewall Rule to “Block” that IP address should work.

Thanks sdayman! How do I block access for any IP not on the ips list? I wasn’t able to easily find that function, sorry I am new to this.

You would need to ask your host if they can support this.
