You need to run two instances, one pointed at each interface, to see all the traffic. And with this problem with ntop, you need dummy IP addresses on all the interfaces. > though that's not a common configuration. (It's not uncommon either; one scenario is when you have a small subnet from an ISP, want to place a packet filter between the router and the LAN, don't want to burn most IP addresses, and want the filter to be manageable in-band.)
