[squid-users] squid wccp problem - packets not redirecting to squid

Hi all,

I've a problem with redirecting wccp packets to squid.
What I've done is setup gre1, loaded module ip_wccp,
and I'm using mandrake 10.0, cisco IOS 12.x

The problem is that the cisco router shows that the
cisco has registered the server as cache-engine, and
the port 80 traffic is passing through to my gre1.
However, it doesn't get passed on to my squid (running
at port 8080). I've already setup my iptables rule and
there's no firewall blocking.

iptables -A PREROUTING -p tcp -i eth1 --dport 80 -j
REDIRECT --to-port 8080
(my interface is eth1)

this is the tcpdump from my server (tcpdump -i gre1)
...

xxx.xxx.xxx.xxx.http: S 2830852043:2830852043(0) win

... and this (tcpdump -i eth1 port 80)

but tcpdump port 8080 shows nothing...
this is squid's cachelog
...
Accepting WCCP messages on port 2048, FD 15.

Any ideas?

Thanks.
