Hi

I have a problem with squid running wccp. For transparent proxy it works
fine if I set the gateway of my workstations
point to the squid machine. However the router does not seem to redirect
wccp packets to the squid.
In my opinion, the problem seems to be related with the ip_gre.c patched
file because the
gre counters shown by netstat -i -v are 0, but I am not sure and would
be very grateful if somebody could help me

I am starting the tunnel with the following command

/sbin/modprobe ip_gre
/sbin/ifconfig gre0 10.0.0.1 netmask 255.255.255.255 up

here is my squid.conf

httpd_accel_with_proxy on
httpd_accel_uses_host_header on
httpd_accel_host virtual 80
wccp_router 62.240.54.5
wccp_version 3
wccp_incoming_address 195.126.56.2

Here is a show ip wccp on the cisco 3660 router

gate1#show ip wccp

Attached is the patched file ip_gre.c that I am using and the kernel
used is 2.4.18-5 on redhat 7.3 box and squid was installed with rpm from
redhat. Machine is live updated to the most recent versions
