here is the description of my network (keep in mind it is a 256k going
up to 448k in two weeks)
 
Hi

I am an ISP running FreeBSD as a firewall and as a Mail Server. My
problem is that I am not able to monitor the amount of traffic that user
are using on my network.

My network looks like this: My Link comes in on a Cisco 805 from the
router it goes to the first NIC on the Firewall from the second NIC it
runs into a switch  and then to the network.

What I am looking for is some app that could show me live what ip on my
network is utilizing what part of the bandwidth.I know there are a
million apps available but I need to see from IP ???? to IP ???? ????
kb/s and then see how much of the 256k is still available. Don't laugh
!!I have a 256k Diginet connection and I would like to see who is
killing my network. I do get live graphs from my upstream supplier but
it shows the line utilization from my router and not who is using
what.So I can't be proactive in solving speed issues I need to wait for
it to happen and then by a process of elimination disconnect segments of
the network and see when the graph drops.
