Hi,
        I am having problems with wccp, see my email :

        STill no go, i am at witsend here, trying to get it going, here is
my cfg (i even installed the latest ver of RH on the server, still no go)

Cisco :

ip wccp enable
ip wccp redirect-list 110

int e 0 :
ip web-cache redirect

access-list 110 permit ip 203.19.222.0 0.0.0.255 any
access-list 110 permit ip 203.34.144.0 0.0.0.255 any

Linux :

/sbin/modprobe ip_wccp.o
echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/ipchains -A input -j ACCEPT -i lo
/sbin/ipchains -A input -j ACCEPT -p tcp -d 203.19.222.2 80
/sbin/ipchains -A input -j REDIRECT 8080 -p tcp -s 0.0.0.0/0 -d 0.0.0.0/0
80

Squid :

wccp_router 203.19.222.14

# TAG: wccp_version
# According to some users, Cisco IOS 11.2 only supports WCCP
# version 3. If you're using that version of IOS, change
# this value to 3.
wccp_version 4

To me the lot looks fine, when i change the default gw on the machine, i
am testing it with, and no proxy it works fine, its when i change it back
to the main router, its as though its not redirecting at the cisco end,
that I am not to sure on. When i debug the logging for ipchains, the
packets arent even getting passed fro the cisco to the ipchains rule, so i
cant see that there is communication between the cisco and the squid box.

I am using IOS 12.0(11)

Still nothing comes up in the squid logfiles for my ip address to say i am
accessing the proxy.

Any ideas?
