CentOS Linux release 7.4.1708 ISPConfig Version: 3.1.8p1 Recently I reconfigured from Bastille to UFW. Overall all works fine with UFW, except... upon reboot UFW is inactive. Once I turn firewall off in ispconfig and then back on, all is ok and working fine. Including the correct firewall ruleset. Except on reboot ufw is inactive again. Setting up ufw in system V startup makes no sense either since the rules are missing to configure it. What am I missing ;( ?
