osx - ipfw on Mac OS X 10.8 - Unix & Linux Stack Exchange I'm trying to setup local transparent proxy with ipfw and squid and ran into some problems. I have a single rule 00100 fwd 127.0.0.1,3128 log tcp from any to any dst-port 80 but it either gets into infinite loop or doesn't work for some other reason. There's a ipfw: 100 Forward to 127.0.0.1:3128 TCP 172.17.244.135:56788 74.125.232.0:80 out via en0 message in system.log when I curl something Need some help with terminal?
