Trafic Counter

[Ian Barnes]

Hi,

I am running FreeBSD 4.8 with squid v 2.5_2. It is only active for one
ethernet card (I have 3). I am using IPF, with IPNAT to do the NAT

What i would like to know, is how could i count the trafic through that
ethernet card, and that one only. And can i possibly set a limit as to the
amount of trafic they are allowed to use. Like say 200meg a month or
something?

Thanks for the help.

Ian
