In my home network I have 3 PC's and a handful of Wireless devices. The LAN itself is made up of HP J9029 Web Managed Switches. All devices have a Static IP address. My ADSL Modem/Router is a Netcomm device, and all Internet traffic travels through this. This ADSL Modem also supplies my Wireless service. I recently consumed my whole months ISP data allowance in 3 days. I suspect that one of my devices was the culprit. So, I'm looking for an Applicaion that will monitor the Network traffic traversing through to the ADSL Modem and can reprt on the usage being made, by IP Address. My Switches have the ability to "mirror" a port, such that I expect to be able to provide a LAN Packet stream to this Application, where it can be inspected to produce, said report.
My question is, does Norton have such a product?
If not, has anybody come across an Application that would be suitable?
