The best firewall with IP and MAC block option
I have linux mint, which is Ubuntu but with all the drivers installed.
I want to know what is the best firewall for linux. I use litespeed web server enterprise.
I want it to prevent intrusion attacks. DoS attacks.
I also want the option to maybe have online management, but will probably not happen because I don't have apache.
I want the option to block IP and MAC addresses.
What does everyone think is the best firewall?
