Hi Henrik:
Thanks for your response. That was the first thing I tried, actually,
and when I couldn't get it to work I enabled both ip_wccp AND ip_gre, as
per this how-to (which I realize is a bit dated):
<http://www.sublime.com.au/squid-wccp/>
But based on your suggestion, I tried again with a new kernel (one
without GRE compiled in) and only the ip_wccp module loaded. It worked
like a champ!
As an FYI, I've included a tcpdump of what the packet output looks like
now, in the hope that Google will chronicle it and save someone else
from asking the same question ;-)
Thanks for your help, Henrik.
