Example configuration files were installed to '${EPREFIX}/etc/fwknopd/'.
|
|
Please edit them to suit 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.
