| I don't think it's the case of allowing a specific port on a specific IP, but it's more the case of the server listening on a specific IP. I assume it is SSH you wish to do this, you can find this option in the configuration of SSHD.

| Firstly, enable the port in your firewall configuration.
In the file, /etc/ssh/sshd_config, you will see many lines. To listen on multiple IPs, you need to duplicate the ListenAddress setting like so:
Code:
ListenAddress 1.2.3.4
ListenAddress 1.2.3.5
ListenAddress 1.2.3.6
For each IP, you add a new line. If the ListenAddress settings are commented out or not there, it will listen on all IPs.
P.S. Don't forget to restart the SSHD service

| You can enable SSHD on another port by adding another Port directive like so:
Port 2050
(for example)
Then, you can add firewall rules like this:
iptables -I INPUT -s IP.IP.IP.IP -d IP.OF.SSH.SERVER -p tcp --dport 2050 -j ACCEPT
iptables -I INPUT -s IP2.IP2.IP2.IP2 -d IP.OF.SSH.SERVER -p tcp --dport 2050 -j ACCEPT
iptables -I INPUT -d IP.OF.SSH.SERVER -p tcp --dport 2050 -j DROP
