Well to this day I dont understand which particular zones must have smb instances added, and which of the three smb instances must be added where, for it to work, so I added them to all those I saw were permissive, probably overkill. A button, option really, that one chooses to click or not, to auto add it to some proper preselected default zones for it to work right out the box if the user says yes, would be fine.
