1) really fast (to install and to see first results) solution:

	/usr/ports/net/ntop
	http://www.ntop.org/ntop.html
	(but I have no idea how it will behave on a busy
	wire - seeing a lot of connections - over a longer time)

2) MRTG

	/usr/ports/net/mrtg
	http://www.mrtg.org

	provides you with some scripts in it's contrib/
	to monitor bandwith by using 'ipfw count' rules
	(it produces nicely configurable graphs in a min. 5min interval)


best regards,

Frank Reppin
