you could put a HUB (not a switch) between your network and this router,
then hang a dedicated linux system on it that was running NTOP, and find
out all KINDA cool stuff....
-[ISP router]------[hub]----------[your existing switch]---your network
[ntop monitor system]
alternately, if your existing switch is a managed switch, you may be
able to set a specific port on it to be a monitor or mirror port, and
connect the ntop monitor to that port.
