Друзья.

Есть сервер под управлением Debian.
Периодически появляется проблема связанная с тем что с одного айпи
начинает валится уйма запросов к серверу + из-за этого вырастает LA .

Например:

|cat production.log | grep 178.95.42.226

В настройках nginx поставил лимит

|
limit_zone http $binary_remote_addr 1m;
limit_conn http 10;

При тесте Siege - nginx успешно дропает соединения больше 10 в единый момент времени.

В моем же случае такое условие не совпадает.
Можно ли как сделать так|- если с одного айпи в течении минуты есть больше 30 обращений к серверу - то заворачивать злодея на страничку - заглушку?
|Или как с таким бороться?
