I intend to get a little further than this, I want to even add gre to it so then it will hopefully behave like a Cisco doing WCCP2 with an external squid box with wccp2 configured. Purpose is modest :- Use it to check if the squid is set up correctly without disturbing existing network. Maybe you could be a little more specific about if you were to do it, how would you go about doing it. More specifically when the squid is 'tproxy transparent', ie when the forward path is spoofed, how to you handle the routing of the return path. Regards.
