I want to implement a cobalt raq 4 cache appliance in our network. We have a catalyst 6000 switch with 6 vlans. I don't want to configure the raq as traditonal proxy, rather I want to use the transparent mode. Would a class access list be the best solution, using one interface, to route the traffic through the raq? We also have a router from our ISP which we don't have control over it. That's why I am not using the second interface card. Any input would be appreciated.
