toms hardware /networking just did a review of Omnipeek personal and
they seemed to like it.  I haven't tried it yet, but it looks good from
the review.  They compared it to the wireshark (ethereal) program
mentioned previously.

Hope it helps.

I'd recommend checking out ntop.  Easy way to get it going would be to
use the virtual appliance here:
http://www.vmware.com/vmtn/appliances/directory/388  Not Windows, but
easy to run VMware Player or Server on Windows and run it that way.

On the switch m0n0wall's LAN is connected to, you'll need to mirror
m0n0wall's LAN port to the port the ntop machine is running on.  If you
don't have a managed switch, you'll have to connect a hub or network tap
between m0n0wall and your internal network and plug the ntop machine
into that.
