Hi, I want to configure squid tproxy as external device.So for that what changes do i need to follow in iptables rule and policy routing from OS side? Current Lab setup: WAN ROUTER | | | switch-------LINUX MACHINE ( configured as router ) ------ end users | | squid Currently i tried to follow squid wiki steps to configure tproxy.And i can see traffic in squid access log but browsing not happening . even i m not seeing any traffic in iptables for tproxy rule. Kindly guide me to solve this problem. I want to deploy squid box as external device for getting cache gain.So for that do i need to change anything in iptables or policy routing? OS : centos 6 32 bit squid : 3.1.4 Thanks, Benjo
