        I was running a tcpdump looking for the gre data, and accidentally
didn't specify the wccp0 interface, so it defaulted to my eth0 interface.
It appears I'm getting the GRE packets over eth0, NOT wccp0! When I decode
them, they are all SYN's to port 80 at various websites.

        I go back to wondering if the highest IP on the router, which is
also the default route for the cache box, is causing it to ignore the tunnel
and just send it locally..
