CSF Firewall configuration for single domain name

Question

Hello all,

i'm running on a Dedicated server and i have two IPs

Is it possible to block some ports for just one of the IPs via CSF firewall?

What i mean is that i have two domains configured to two IPs

let's say example1.com is on ip 1.1.1.1 and example2.com is on 1.1.1.2

how can i block some ports for IP 1.1.1.2 and still have the same ports open for 1.1.1.1 ?
