TCP Traffic Path Diagram
Hello,
I just wanted to say that the FLOW_INIT is triggered after packet filter. It was well represented in version 0.1 however in version 0.5 the "Packet filter on VLAN" was moved down below "AFM/TMM Processing begins" .
Could you please explain why you made such a modification ?

are you really sure Karim? logically i would say that FLOW_INIT doesnt trigger if a packet filter already has blocked the connection to start with.
this is where What Lies Beneath determined the situation i believe: https://devcentral.f5.com/questions/the-flow_init-event-and-event-order
if i test this and block traffic with a packet filter i don't get a FLOW_INIT event, if i remove the packet filter i get it, tells me the diagram is ok.

boneyard, We are saying the same thing: If the packet filter blocks the packet we'll not get the flow init event.
However, the diagram v0.5, the flow_init box is represented before the packet filter box. Which seems to say that whether we're blocked or not by packet filter we always get the flow init event (which I think is incorrect)
You can see that in v0.1 of the diagram, the flow_init box was set after the packet filter box, which make more sens for me.
Thanks,
