Dear Every One, I am implementing fully transparent squid using TPROXY and I followed this http://wiki.squid-cache.org/Features/Tproxy4 document but I could not get it works properly. My Configuration is Fedora 16 x64 bits, Cisco ASR 1006 (IOS XE 2.06) and squid version 3.1.19. Since I use mask assignment method with L2 redirect and return, what should I make change at following directives? wccp2_forwarding_method 2 wccp2_return_method g2 wccp2_service dynamic 80 wccp2_service_info 80 protocol=tcp flags=src_ip_hash priority=240 ports=80 wccp2_service dynamic 90 wccp2_service_info 90 protocol=tcp flags=dst_ip_hash,ports_source priority=240 ports=80 -- Best Regards, YOUK Sokvantha Tell: (+855) 89896589 email: sokvantha@xxxxxxxxx
