Snort in Transparent Bridge Mode

[Streaker]

Greetings.  I work in a heavy Cisco shop that is in need of an IDS solution.  The Cisco solution is quite expensive and I believe that it can be accomplished with PFSense using the Snort package.

I run PFSense at home and love it.  Works like a champ with everything that I want it to accomplish.

My question is this:  Am I able to load Snort in transparent bridging mode and run it on the link between my firewall and my LAN?  And have the rules work?

Thanks in advance.
