Are these clients on the local network?  If not, then this will not work.

Assuming the clients are on the local network, here is the command you need:

iptables -A INPUT -m mac --mac-source 00:0F:EA:91:04:08 -j DROP

Replace the MAC address with the ones in your list and you should be all set.

Just re-reading, if you only want to block on port 8080, you need to modify the command or you can open only the ports you want them to access using something like this:

iptables -A INPUT -p tcp --destination-port 22 -m mac --mac-source 00:0F:EA:91:04:07 -j ACCEPT

which would allow access to SSH from the specified MAC address.  Be sure to put the allows before the rejects in your rules list.

Hi mattvmotas,

I am having 30 MAC address in mac.txt file. iptable can able to read 30 MAC address from mac.txt file?
Matt VCommented:
You will have to enter 1 iptables command for each address.  You could probably write a bash script to read the file and issue the commands, but for 30 addresses, I would just type them in.
