Why? In General, then it is necessary to dig towards iptables, and not in the direction of the daemon, since the daemon is nothing more than a harness around iptables. Moreover, the functionality of the firewall is part of the kernel, i.e., as such the process there is not, and the same iptables is a utility configuration, and the firewall is netfilter)
