Hi Martin

One of the best tools I've found for monitoring network traffic is ntop
- www.ntop.org

It will give you totals, plus protocol breakdowns for each packet it
sniffs. If you've got a copy of a newish SuSE, it's in the distribution.
Ok, it possibly means having a separate machine for monitoring, and
either a managed switch that can mirror all traffic to one port onto
another port (the ntop machine needs to see all traffic that flows
through m0n0) or a hub (NOT switch) with the network/m0n0wall/monitoring
machine on it only. Eg:

M0n0----hub--------to rest of network
         |
        Ntop

There's an ntop add-in for Smoothwall if you look through their forums.

If you want some screenshots of ntop in action, let me know.

Richard
