What an internal packet flow looks like?
-
Mikrotik RouterOS which I've dropped in favour of pfSense had a wonderful documentation including detailed description of internal packet flow.
Can anyone tell me how all this works in pfSense?

There are some diagrams like that in the book, but nothing that detailed. Basically just showing how and when NAT, filtering, etc, are applied with respect to each other. If you can find such a diagram for pf on freebsd, it would be the same (or really, really, close at least).

It's exactly what I need – just a general directions and an order of stages!
Is some schematic like that can b found somewhere on wiki or something like?

Somewhere on forum a question about something like "build world from freebsd codebase" was answered like "impossible because of many deep changes and other platform inclusions". :)

There are lots of patches against FreeBSD, sure, but I don't believe that the fundamental underlying order of things has been changed.
I don't recall if there is a diagram on the wiki or not. I know it's been explained a few times is various places on the forum, but I don't recall seeing a graphic. The book is a far more complete and accurate set of documentation 8)
