W2K server with 2 network cards, one to cable modem, one to internal LAN. Users from internal LAN acces Internet through NAT and cable modem.
Traffic is counted with DU-meter, last version, only the right interface's traffic is counted (the one with the cable modem connection).
Last few days a 5 KBytes steady traffic is counted all the time.
Asked the cable modem company, and they say this is normal because they scanning the network. I can see those broadcast packets with Network Monitor all day long.
I don't wan't to use Performance Monitor or other hardware.
So I need another (smarter) application to count the traffic without the broadcast packets.
Can you help ?
