I have PRTG Traffic Grapher running on a system to help monitor bandwidth/data usage on a DSL line.
According to the ISP, 3GB of data went over that line on the weekend, and sure enough PRTG shows this on the ATM port of the router, but dosent show anything near that amount on the LAN port of the router. (monitored via SNMP)
So where has that data gone ? I thought anything being downloaded/uploaded via a workstation on the network would be recorded on the LAN port as well as the ATM but not showing anywhere. Running Webmarshal as well and thats not showing any usage but its easy to bypass really.
