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 ?

you should try zonealarm It's a software firewall. It is really easy to use, has lot's of options, and the standard version is free! http://www.zonelabs.com/store/content/catalog/products/sku_list_za.jsp?lid=pdb_za1
you can put all the ip adresses or a range of ip's into your trusted zone for the computers that you want to have free acess to your services.

did you mean on a MS W2k Server?
If thats what you meant then yeah... I have used it succesfully on windows 2k. It can be a little tricky to figure out but the help files are good. and a lot of people use zone alarm so you should be able to find more help in forums or here on EE.
