Squid3 transparent proxy breaking firewall rules



  • My firewall rules directs lan traffic through various gateways (openvpn clients and wan) depending on source ip or destination subnet. I want to setup squid3 as a transparent proxy to monitor web usage and get lightsquid reports. In doing so, I notice that some sites are blocked and others are not using the proper gateways.

    How can squid3 acting as a transparent proxy break firewall rules?
