What kind of router?  A Linux box or a commercial hardware router?  If
it's a Linux box I'd recommend ntop[1]. If you have a hardware router
is capable of exporting NetFlow data I'd look at either ntop[1] or
flow-tools[2].  If your hardware router isn't capable of exporting
NetFlow data I'd recommend sticking a Linux box in transparent
bridging mode in front of the router and using ntop[1].
