Is it possible to give the real address of the connected "client" through SQUID proxy?

Question

Squid

Colleagues!
There was a task to give through transparent squid real IP of "client". No security, no anonymity, with which he came to squid with this and went on the Internet. Is it possible? Google didn't give a definitive answer.

Answer 1

Адрес клиента обычно отдается в заголовках Forwarded и/или X-Forwarded-For.

Answer 2

Прокси - это программное обеспечение, работающее на 6 и 7-ом уровнях модели OSI.
Оно не может оставить IP неизменным.
