    I hope too. I don't have my particular setup running at all.

    I'm using the ip_wccp module without any patches. My problem is that
squid doesn't "understand" what it receives. I have defined several ip
tables to redirect packets but seems to not work.

    WCCP encapsulates redirected packets in GRE (Generic Routing
Encapsulation) and send them to the Cache box. UDP port 2048 is the
"ststatus port", I think. The ip_wccp module strips the GRE header from the
packets it has received. The only one difference between this and the ip_gre
is that you can send GRE packets because you can define a new interface and
routes.
