Squid is version squid-2.5.STABLE3-6.3 Are you using WCCPv1 or WCCPv2? Squid-2.5 doesn't support WCCPv2 without some patching - and if you're going to patch I'd suggest just upgrading to Squid-2.6.STABLE5. > webc2:~# lsmod > Module Size Used by Not tainted > iptable_nat 22744 1 (autoclean) > ip_conntrack 29736 1 (autoclean) [iptable_nat] > ip_tables 16544 3 [iptable_nat] > ip_gre 11968 1 > > webc2:~# iptables -t nat -A PREROUTING -i gre0 -p tcp -m tcp --dport > 80 -j DNAT --to-destination 150.125.125.114:80 Make sure you've enabled ip routing/forwarding and disabled rp_filter in /proc . > webc2:~# cat /etc/squid/squid.conf > --trimmed-- > wccp_router 150.125.125.98 > http_port 80 > httpd_accel_host virtual > httpd_accel_port 80 > httpd_accel_with_proxy on > httpd_accel_uses_host_header on Looks good; but thats for wccpv1. An example working WCCPv2 config can be found in the Squid Wiki. Its for Squid-2.6 and WCCPv2. Adrian
