I want to find out how much bandwidth individual users on our small company network use accessing the internet. We have a highspeed wireless router(Linksys) that relays the signal over to office. It has to pass through our VPN firewall router in the office (Netgear FVS318). I thought I might try monitoring the VPN Router with Passeler's Traffic grapher or Alchemy Network Monitoring software but it seems they both operate on SNMP and for the life of me I can't find that feature in either router.
What's the best way to monitor employee bandwidth?
