Transparent proxy with Squid.

RouterOS General

Hi to all.

I would like some help in a problem that i have on my firewall.

I have in my network a Squid box running as a proxy , so what i want to do is to get all traffic going out on potr 80 redirect to my squid box on port 3128 like that i can make a transparent proxy.

Here it is my firewall rule on my mikrotik
action=dst-nat chain=dstnat comment=WEBPROXY disabled=yes dst-port=80
in-interface=ether2 protocol=tcp src-address=10.0.0.0/24 to-addresses=
10.0.0.81 to-ports=3128

Every thing look right for my but it does not work if i set the proxy on the web browser work no problem but my firewall rule does not work at all.

I just would like to know if i am doing something wrong.

Thanks for all help.

Try changing squid address (10.0.0.81 to 172.16.x.x eg.) different from 10.0.0.0/24 src-address.

By default (apt-get install squid) squid does not support transparent proxying. You have to compile it yourself with the right arguments to make it work in transparent mode.

Are you sure the problem is not in squid?
