How to make "transparent" squid proxy server?

Question

linux

In the /etc/squid/squid.conf file, when you add a command , the interceptproxy server stops working, when you remove it, everything works right away. The whole line in the config looks like this http_port 192.168.1.10:3128 intercept. I am working on ubuntu 20.04 with squid version 4.1

Answer 1

If you need both a transparent proxy and a normal one, then you need to have a line with intercept, as well as a regular
example

http_port 192.168.1.2:3128

# transparent configuration ports
http_port  192.168.1.2:3129 intercept

well, plus, this is all with iptables
, and also, I almost forgot, you want to dance with SSL, there you will also need to add about ssl-bump.

Answer 2

To make squid transparent, you need to google one of the instructions on how to make squid transparent and use it to make it transparent.
It will obviously contain many more points than one addition of intercept
. And if it is good, they will also indicate to you that it is better to start a separate port for a transparent proxy, since adding an intercept will break an opaque proxy.
