RE: RE: RE: [squid-users] WCCP help

Thanks Venkatesh and Damien. Looks like squid is NOT accepting the packets.
The debug output is showing the ICMP unreachables. My next question is, how
do I compile in the ip_wccp.c module? I'm running Redhat 8

Thanks in advance,

John H.

Here is quick check list for enabling WCCP with Linux/Squid

1. You need wccp module for the kernel or you need a patched GRE kernel. I
don't have the URL for ip_wccp.c with me right now. You should be able to
find it in list archives or google "squid wccp"

2. Please note Cisco WCCP redirects the www packets to the cache box and
still packet destination is port 80. You need to have a redirect entry in
iptables in Linux box.
/sbin/iptables -t nat -I PREROUTING -p tcp --dport www -j REDIRECT 3128

3. You need to enable the wccp in squid.
