Squid Interception Proxying Troubles

[Erik Bixby]

SquidGuard runs fine.  With a browser configured to use the proxy
directly, everything works.  It's only when trying to intercept
traffic that things fall down.  I can get the packets from the client
to the web server to either the Ethernet or GRE virtual interface on
the Squid box, but Squid does nothing with them.  That is my problem;
how to get Squid to act on HTTP requests that are neither originated
from nor destined for it.
