The Firewall Rule "Direction" Option in OPNsense

I have seen seen some confusion around the "Direction" option when creating firewall rules in #OPNsense. In this video, I attempt to clarify what the Direction option means and a real world example for illustration purposes (the example is likely something you shouldn't actually do but it does help demonstrate the in/out direction of firewall rules). Most of the time you will want to use the Direction of "in" since it is more efficient on the CPU since there are less packets to process. 00:00 Introduction 00:31 Direction: In 01:04 Direction: Out 01:37 Diagram Example for Direction In 03:05 Diagram Example for Direction Out 04:49 Real Example for Direction In 05:40 Real Example for Direction Out 08:00 Conclusion EP23
