Actually, if you are using a switch, then the LAN interface on the m0n0wall
will ONLY ever see traffic that is directed to it - specifically directed by
IP, and also broadcast. So it will never see general network traffic.
Also, even were someone still using a hub, it would see this traffic, then
it would be dropped well before the firewall rules/shaping rules get to see

Yes, this is something I'm seriously considering here.
