I found a thread about this topic yesterday via Google. It was on
the FreeBSD-ISP@frebbsd.org mailing list sometime in 2005 if I
remember correctly.
They came up with a few options
netflow,
counting rules in IPFW/pf/ipf
netstat -rni ( which gets you packet counts,
-rnbi gives you in-bytes and out-bytes)
bandwidthd (in ports I believe)
I suppose ntop could do similar things.
My favorite option was netstat -rnbi | awk '{print $8,$11}' and
feeding that to MRTG. I have not gotten it implemented yet.
One consideration is that on FreeBSD 8 and older, you don't get out
traffic per IP address with netstat, as far as I can tell. We're
moving to FreeBSD 9 pretty quickly anyway.
