Our "campus" is comprised of five undergraduate and two graduate institutions. The "campus" has its own class B address and that IP space is divided among the various institutions.
The cost of the internet connection is divided based on the amount of traffic each institution does.
What I need to be able to do is to generate a report for a specific network range to get a "total" traffic in/out for that institution.
The custom report gets part way there in that it I can specify a network range, but it only lists "Top xxx" and does not included "totals".
