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: ===================================================================================== ip wccp 80 ip wccp 90 ! ! ! interface GigabitEthernet6/1 description *** Connection to Core Router *** Connection to Core Route ip address 202.125.64.251 255.255.255.248 no ip redirects no ip unreachables no ip proxy-arp ip wccp 90 redirect out ip route-cache flow no ip mroute-cache ip ospf flood-reduction no cdp enable ! ! interface GigabitEthernet6/7 ip address 203.83.175.209 255.255.255.252 ip access-group 125 in ip access-group 173 out no ip redirects no ip unreachables no ip proxy-arp ip wccp redirect exclude in ip route-cache flow no ip mroute-cache no cdp enable ! ! interface GigabitEthernet6/9 ip address 203.191.33.23 255.255.255.0 ip access-group 125 in ip access-group 173 out no ip redirects no ip unreachables no ip proxy-arp ip wccp 80 redirect out ip route-cache flow no ip mroute-cache ip ospf flood-reduction no cdp enable ! --------------------------------------------------------------------------------- mynet#sh ip wccp Global WCCP information: Router information: Router Identifier: 203.83.175.251 Protocol Version: 2.0 Service Identifier: 80 Number of Cache Engines: 1 Number of routers: 1 Total Packets Redirected: 16685 Redirect access-list: -none- Total Packets Denied Redirect: 0 Total Packets Unassigned: 4342 Group access-list: -none- Total Messages Denied to Group: 0 Total Authentication failures: 0 Service Identifier: 90 Number of Cache Engines: 1 Number of routers: 1 Total Packets Redirected: 0 Redirect access-list: -none- Total Packets Denied Redirect: 0 Total Packets Unassigned: 0 Group access-list: -none- Total Messages Denied to Group: 0 Total Authentication failures: 0 mynet#
