Если на машине где в качестве ОС установлена windows, указать в браузере прокси сервер, то вроде как прокси работает.
Если же попробовать на другой машине, где стоит Ubuntu через Iptables пустить трафик через прокси
iptables -t nat -D OUTPUT -p tcp --dport 80 -j DNAT --to-destination %PROXY_IP%:3128
то прокси сервер отдает ошибку в браузере
ERROR
The requested URL could not be retrieved
While trying to retrieve the URL: /
The following error was encountered:
* Invalid URL
Some aspect of the requested URL is incorrect. Possible problems:
* 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
Подскажите пожалуйста, как настроить все правильно ? И сделать прозрачный прокси сервер?
