Hello, My system is still not working ! currently i am trying to see if my box is configured correcty, tproxy, squid 3.1, and the iptables any way i can test to see if all is well ? so once this one is set i can move and experiment on wccp ! i tried to put the box as gateway for some pc, but the pc could not browse, time out error, they can only browse if i remove the routing config ip rule add fwmark 1 lookup 100 ip route add local 0.0.0.0/0 dev lo table 100 but then no caching occurs, pointing to the box as proxy server on browser works, and also caches. any help here ! It would help if somebody can post some configs, so i can make this work ! either as gateway or using cisco wccp. Do i need any other rules on iptables if i want to use as gateway ?
