All, Our WCCP version 1 was running for 2 years then getting problem with hotmail.com authentication. Someone suggest me to use WCCPv2 to solve the issue. I tried to run WCCPv2 on linux 2.4.32 with wccp modules version 1.7. After configuring Squid and Cisco router (more or less was same as WCCPv1), I saw that Squid can talk to Cisco. But there are no packet were redirected. AFAIK, wccp module (v 1.7) support WCCPv2, but I am curios why the packet redirection was not happen. Currently, I don't have plan to use linux 2.6.x. Hope you would suggest me how to solve such problem with using linux 2.4.x. Your help is very appreciated and waited for. Thank you so much and best regards, Awie ===SNIP=== Global WCCP information: Router information: Router Identifier: W.X.Y.Z Protocol Version: 2.0 Service Identifier: web-cache Number of Cache Engines: 1 Number of routers: 1 Total Packets Redirected: 0 Redirect access-list: squid-wccp Total Packets Denied Redirect: 7346 Total Packets Unassigned: 0 Group access-list: squid-cache Total Messages Denied to Group: 0 Total Authentication failures: 0
