i see the GRE packets.. protocol 47 too (in both tcpdump and the firewall accept logs).. but no port 80 packets.. http packets are only seen when using policy routing, and now wccp..
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.
