Как защитить вебсервер стоящий за pfsense



  • Слишком много соединений открывают типо таких на 80 порту

  • Добрый.

    1. Есть в настройках правил fw пункт, к-ый ограничивает кол-во подключений в сек.
    2. В настройках любого веб-сервера также имеются директивы, к-ые позволяют ограничивать кол-во подлючений на еди. времени.


  • Вы имеете ввиду зайти на правило которое отвечает за порт 80 и 443?



  • @werter что-то не могу там найти такой пункт



  • @werter в общем почему то у меня нету такого пункта Maximum new connections per host (TCP only).



  • @борис
    Находится в Firewall / Rules / Edit в разделе Extra Options Display Advanced

    И советую почитать зту ссылку
    http://salf-net.ru/?p=494



  • @oleg1969 в последней версии pfsense этого пункта нету вот снимок экрана https://tvoyadres.ru/1.jpg



  • В общем разобрался там немного внешний вид изменился этих полей.
