Hi Loïc,
Thank you for your tip.
I found the solution.
This helpt me.
Interception Proxying with PF
=============================
To configure an interception (a.k.a. "transparent") proxy, Squid should be configured in ${SYSCONFDIR}/squid.conf to bind to a specific address, for example:
http_port 127.0.0.1:3127 intercept
On the machine running Squid, add a firewall rule similar to this:
pass in quick log inet proto tcp to port 80 divert-to 127.0.0.1 port 3127
