Hello,
the output of the debugging is as such:



*Jan 4 23:16:43.205: WCCP-EVNT:D90: Here_I_Am packet from 192.168.0.183: service not active *Jan 4 23:16:43.205: WCCP-EVNT:D80: Here_I_Am packet from 192.168.0.183: service not active

what service is that?!

ifconfig gre0 192.168.0.183 netmask 255.255.255.0 up
#this is the same ip as my eth0

----------------------------------------------------
gedit /etc/sysconfig/iptables

#added:

gedit /etc/squid/squid.conf

#edited/added the follwoing:

Cisco router 2811 side:

conf t
ip wccp version 2
ip wccp web-cache

int f0/1 (Lan interface)
ip wccp 80 redirect in
ip wccp 90 redirect out

Hi Roland,

Have you had a look at the WCCP debugging messages on the Cisco?
eg. on the cisco
   debug ip wccp events
   debug ip wccp packets
   terminal monitor

That should give you some indication of wccp activity, also what does "sh ip wccp web-cache detail" show?
