Не работает прозрачны прокси SQUID
Добрый день. Есть проблема, с которой я разобраться не могу.
Дано: Сервер на FreeBSD 10 пакетный фильтр PF squid 3.5 Проблема: При настройки прозрачного проксирования выдается ошибка на хосте (в браузере) В чем проблема? Помогите разобраться, пожалуйста! Ошибка в браузере
ERROR
The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: / Invalid URL Some aspect of the requested URL is incorrect. Some possible problems are: Missing or incorrect access protocol (should be "http://" or similar) Missing hostname Illegal double-escape in the URL-Path Illegal character in hostname; underscores are not allowed. Your cache administrator is webmaster. Если устанавливать в браузере настройки сквида, то все нормально - работает. Конфигурация squid

Попробуй transparent вместо intercept и указать реальный ip
|
В версии SQUID выше 3.2 используется intercept, но замену transparent выполнял. Но ничего не помогло. Замену ip адреса http_port 192.168.20.1:3128 intercept выполнял. Так менял параметры на pf.
Что делать? |
Порт 80 перенаправлен на 3128?
|
tangichhan, для чего требуется прозрачность? Как с https поступите?
|
для https будет NAT, для остального трафика прокси
|
Кусок из squid.conf
=== # Адрес и порт для входящих подключений # При прозрачном проксировании может использоваться для управления кэшем http_port 3128 # Локальный интерфейс, для трафика, перенаправленного брандмауэром http_port 3129 intercept === |
