Hello, I have an existing firewall and would like to use squid to do url filtering and blocking. What is the best setup for this 1or 2 nic cards and if to setup squid as a transparent proxy or a proxy. What is your opinions to those who are already using it under my present setup. I have 4 sites connecting to the internet through one site and that is where the firewall is and now I would like to start filtering and blocking. Any ideas? Thanks
