Example configuration files were installed in /etc/fwknopd directory.
Please edit them to fit your needs and then remove the .example suffix.
fwknopd supports several backends: firewalld, iptables, ipfw, pf, ipf.
You can set the desired backend via FIREWALL_EXE option in fwknopd.conf
instead of the default one chosen at compile time.
