I still don't get it - how do you define rules by PID and make it work after the next reboot? Won't the PID change for the process in question? I assume by PID

- egberts1 3y agoIt may not be obvious but one (lesser) application is to block all ports to PID 1 ... for logging purpose. Most of this kind of firewall rule get created after such executable starts ... by a dedicated firewall daemon monitoring the operating system's PID state (creation/deletion/child).
