[squid-users] WCCP2 not working with squid 3.1.10 with tproxy

Hi,
We are following Squid's wiki to configure Squid 3.1.10 with TPROXY and wccp2.
http://wiki.squid-cache.org/Features/Tproxy4#Minimum_Requirements_.28IPv4.29
But no fruitful result yet and nothing showing at access.log.
I guess we meshed up with CISCO, following is the configuration,
looking forward for correction suggestion:
