I successfully configure tproxy all the steps. (Patching Centos, Patching iptables, Building squid). And also WCCP configuration with L4 WCCPv2. When I trying check gre0 tunnel with any packet flow but don't found any request. My error showed..............

Dear Nocolas, Please see the router status... Cisco IOS Software, 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 12.3(14)T 4, RELEASE SOFTWARE (fc2) ROM: System Bootstrap, Version 12.3(8r)T7, RELEASE SOFTWARE (fc1) It's also mention that another one my proxy is running with WCCP same router configuration. But currently my project is tproxy configuration with WCCP, it's has not running ok. My question is TPROXY + WCCP anything misconfigured ????
