Hello I want to configure squid to be a Transparent proxy using L3 cisco 3550 switch (without using wccp), so I follow this tutorial http://www.cisco.com/c/en/us/support/docs/ip/ip-routed-protocols/47900-cat3550pbr.html as the picture in the tutorial show: The goal is to redirect all workstations (20.20.20.0) traffic to squid 30.30.30.2 (I have used PC with squid instead of the shown router in the picture) and I set 10.10.10.2 as a web server instead of the router too The redirection have worked well, my question is how can I make squid redirect the HTTP traffic to the web server from the workstation Transparently and return the page from web server to the workstations too?
