Network Monitoring

[klussier at comcast.net]

Hi All,

I find myself in the dis-pleasing position of needing to monitor internet usage in one of our branch offices. I am looking for recommendations on packages for this purpose. What I need to do is put a box between the internal router and the firewall that will monitor the traffic and correlate it. I need to gather information on what internal IP addresses are accessing what websites, how often, etc. (you know, the usual disdainful big-brother type of information). Any suggestions as to how anyone else has done this would be appreciated, I guess....

TIA,
Kenny

PS If you hadn't guessed, I really hate doing this sort of thing.
