Hello. I was wondering if and how it is possible to remove/disable/close specific ports on IP. I have VPS running CentOS and the server has 2 IP's. 1st one is the main IP used by web server, ftp server & ssh. I changed mail server (Exim) IP address to 2nd IP. Currently if I scan my secondary IP it still shows all the ports together. I would like to run all mail services on 2nd IP with ports (25,465,587, etc.) and all other services on 1st IP with ports (80,21,22,etc.). For example if we scan domain or IP ports the results would show only assigned ports for the specific IP address. Is this even possible? And if it is - how can I do that? Thanks in advance.

  Hello @richardev, You could install a firewall management utility such as CSF for this purpose. An example of how to do this with CSF is found on the following post: Block a port on certain IPs using CSF Thanks!
