This may not be the easiest way, but I have used it in similar
circumstances. Iptraf comes with most Linux distros now. With it you
can monitor interface traffic and see byte counts for individual IP
addresses and port connections. I run it on my notebook and tap the
line between the firewall and the inside switch with a hub. Set the
program to run in promiscuous mode and it will track all the traffic on
the wire. Let it run for a little bit, then scroll up and down the list
to see who is racking up the highest byte count. This at least gives
you a quick idea of who is consuming the larger amounts of traffic.
There are also filters to include/exclude certain traffic to help clean
up the amount of traffic displayed.
You can do similar things with tcpdump and ethereal, but they require a
bit more knowledge to sort out and deal with the data to get the answer
you are looking for.
