Packet Flow Query - FW Inspection

L1 Bithead

Hi Everyone,


I've been madly studying the Packet Flow Diagram that outlines the different checks/stages that a Packet goes through via a PA FW and I had a question with the 3rd check in the Ingress phase called 'FW Inspection applicable'. If Inspection is applicable then it carries into the IPSec/SSL VPN tunnel check but if Inspection is not applicable I see it go directly to the Forwarding/Egress stage.


I was hoping to understand what scenarios FW Inspection would be disabled thus triggering this type of path?


Hey Steve, Interesting to hear your thoughts on the "Day in the life of a packet" diagram. That diagram you included looks fairly clear around the absence of the "FW Inspection" Process. 

Any chance you should share that diagram? I'm keen to take a look at it as it sounds more accurate than the "Day in the life" diagram.

Like what you see?
