Hello list,
I am still battling WCCP... My ultimate goal is to get WCCPv2
functioning properly on a RHEL5 box (squid-2.6.STABLE6-3.el5)
2.6.18-8.el5xen -- connected to a Cisco 7600 (with SUP 720) ISO
12.2(18). Since I am having no luck with WCCPv2 I have been using v1.
I have gotten as far as seeing http traffic leaving my gre interface
but I do not see that same traffic on eth0 (my external interface) and
of course the packets do not reach the destination. Here are my
relavant configs:
modprobe ip_gre
iptunnel add gre1 mode gre remote 150.125.125.186 local
150.125.125.185 dev eth0
ifconfig gre1 150.125.125.187 netmask 255.255.255.248 up (I have
tried many variations on IP addresses here. Having a real routable IP
is the only I can avoid seeing ICMP proto 47 unreachable errors on
eth0)

relevant squid.conf:
wccp_router 150.125.125.186
http_port 80 transparent
The tunnel comes up and registers properly with the router. However,
when I try to surf I see packets redirected on the router to squid, I
see gre traffic on eth0 and I see outbound http request on gre1 but I
never see any return traffic on eth0 or gre1.
Any help would be greatly appreciated.
Thank you,
