 Параметр INIT_APPLY_FW=1 разрешает init скрипту самостоятельно применять правила iptables.
 При иных значениях или если параметр закомментирован, правила применены не будут.
 Это полезно, если у вас есть система управления фаерволом, в настройки которой и следует прикрутить правила.
-
+Хелпер-функции для настройки фаервола вынесены в отдельный shell include : /opt/zapret/init.d/sysv/functions.
+Чтобы не копировать текст и не изобретать велосипед можно подключить include из ваших скриптов.
