Previous steps (how this idea was born) on another thread, starting from here:
http://forum.mikrotik.com/t/ready-to-start-my-custom-firewall-rules-journey/184080/1
… working on it …
EDIT: Attached a tentative version.
I tried to align boxes along a grid where rows are Mikrotik configuration sections and columns are Mikrotik configuration actions chains.
Needs to be reviewed accurately, as I may well have made some mistake, as i changed the layout or the original.
Numbering remains the same for the moment (it will be eventually removed unless deemed necessary for some reason) even if a few numbered boxes were removed (12,15,and 19).
Removed, tentative version 2 (actually 3) below.
