Mick Genie ever guide how to allow and block IP, port, etc from iptables, however there is another option which is to block or allow mac address.

MAC address stand for Media Access Control Address and it could be specifically for a network.

To block a mac address, simply run from shell.

iptables -A INPUT -m mac –mac-source 00:11:22:FF:33:EE -j DROP
