I'd like to block specific ports based on the IP used to connect to my (Linux) dedicated server.
For example, I have the following IP's assigned to my dedicated server:
192.168.0.1 192.168.0.2 192.168.0.3
The first IP (192.168.0.1) would be used specifically for administrative purposes, such as SSH, FTP, WHM, and cPanel. This means that I would want things such as port 80 and port 443 blocked.
Then for the other two IP addresses (192.168.0.2 and 192.168.0.3), I'd want to block the following ports: 21, 22, 2083, 2087, etc. This is because those IP addresses would only be used to serve websites, and should not be allowing access to "administrative ports".
I'd assume I'd have to use some sort of
iptables rule, but I'm not exactly sure what.
Also, if it matters, I'm using
