I don't really know - it's sort of the back of my mind talking here...

I seem to remember that there was a kernel patch in the bridge code.  If you
didn't have that patch, then the packets were grabbed for the bridge before
the various filtering and other processes (such as libpcap) saw them.  With
that patch, the tools saw the packets.

I don't see it in the 'Patch-o-Matic' at http://www.netfilter.org/, not even
in obsolete.  Googling for libpcap linux bridge didn't find anything
obvious.

I guess somebody will have to test this.

..does /dev/br0 work now in ntop?  I seem to remember winding
up with listening to either of the 2 bridge nics thru the 3'rd
_non_-bridge nic, which _had_ an ip.  ;-)

..to view traffic coming the same way as the firewall sees
it, simply watch the bridge's external nic.

  Scenarios always come in sets of three:
  best case, worst case, and just in case.
