Hi, You're missing a few things. Please review the FAQ again, here are some hints: 1) Make sure there are no firewalls between your Squid and router (WCCP). 2) Make sure the GRE module is loaded: modprobe ip_gre echo ip_gre >> /etc/modules 3) Create a GRE interface: ip tunnel add gre1 mode gre local <squid-ip-address> ip addr add <squid-ip-address>/32 dev gre1 ip link set gre1 up 4) Add a redirect rule in iptables: iptables -t nat -A PREROUTING -i gre1 -j REDIRECT --redirect-to <squid-listening-port> 5) Make sure Squid was compiled with WCCP-v2 support. 6) WCCP-v2 squid's configuration: wccp2_router <router-ip-address> 7) WCCP-v2 router's configuration: access-list 160 deny ip host <squid-ip-address> any access-list 160 permit tcp <net> <wildcard> any eq 80 ip wccp version 2 ip wccp web-cache redirect-list 160 interface FastEthernet0/0 ip wccp web-cache redirect in Regards, Horacio.
