pfsense/ntop.. is this possible?

[runningconfig]

I want to take a pfsense box I have and use the ntop package as a network monitor that I can just drop on a clients site to monitor traffic, then again I don't even know if this is possible.

I'm not sure how to bridge these interfaces so they will just pass the traffic though one interface and out the other allowing ntop to analyze it and not disrupting there normal configuration.

Isn't there an NTOP package available for PFSense? I would check there first, but I'm pretty sure I have seen it when browsing what was available.
