Then the WCCP control channel should be working properly and the problems
you are seeing is with GRE decapsulation or the way the router have
encapsulated the redirected packets into WCCP/GRE.
You can verify this by asking your router about the WCCP status. You
should see hash allocated to the cache and packet redirection counters
should be non-zero.
Things to do
1. Make absolutely sure you do not have ip_gre support in your kernel,
only ip_wccp. There can only be one GRE implementation at a time and the
two mutually excludes each other.
2. If it still does not work, use "tcpdump -s 1600 protocol gre -w
traffic.dump" until a few packets have been capture and then send this to
me in private.
My bet on where the problem is is 1.
