Not sure if this is what you need, but I guess you are talking about 
a "layer 2" bridged firewall..

Pix OS supports this only from version 7 and pix 501 and pix 506 
cannot upgrade yet to this version (not sure if they will ever be able to)

A transparent firewall like this just sits beside your switch and 
your computer and the only layer 2 traffic that can pass through is 
arp. All other frame will get deencapsulated and a layer 3 (and up) 
access-list will be applied.

This is what is called a transparent firewall as it is transparent on 
your network :)

With a pix 501, you will need to use nat ou pat or simulate a 
"router" with the "nat 0" command...

Hope this helps
