The WCCP control traffic should go over the IP network, not encapsulated
in GRE.

[Arnold Wang] This reminds me the odd thing I ignored earlier which is I
have to define the dummy IP of the router GRE interface as the
wccp_router in the Squid for it to register with router properly. I
thought it was strange, however I chose to ignore it. I think that's the
reason the control traffics go through the tunnel as well.

The rest looks fine (assuming IP addresses on the WCCP interface
actually match the GRE traffic your router sends), and should work from
what I understand. But that kernel is a bit old and it's possible the
WCCP part of ip_gre maybe isn't fully operational there.

[Arnold Wang] That's what I'm afraid. Do you happen to know whether
there's a way to verify the ip_gre module in my system supports WCCP, as
it should be? I have a case opened already with Redhat as well.

Henrik
