Как защитить вебсервер стоящий за pfsense

Борис

Слишком много соединений открывают типо таких на 80 порту

Добрый.

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

Борис

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

Борис

@werter что-то не могу там найти такой пункт

Борис

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

Борис

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

Борис

В общем разобрался там немного внешний вид изменился этих полей.

Добрый.
