Setting Up ASG220 as a Transparent Proxy

Hi,

We currently have an inherited :confused: dans guardian/squid box which i want to replace with a ASG220. I have had a look around without luck for example setups and help with setting these up as a transparrent proxy.

I am basically wanting to have a link from a switch into eth0 which will then content filter all the web traffic and do its magic, before passing the traffic out of eth1 to the back of a cisco pix. :confused:

Im thinking that bridging might be part of the solution but not 100%

Any help/pointers appreciated.
