![]() With a proxy you can add additional information like what users specifically not just IP addresses are eating bandwidth, that is if you get AD integration. Untangle is a linux distribution that's free, easy to set up and manage which does proxying. ![]() ![]() If you want to have for access control over your network and maybe even bloc offending bandwidth hogging traffic a proxy might be another beneficial solution for you. Unfortunately SNMP collectors like Spiceworks and CACTI won't server your purpose as they would collect data from devices like managed switches and provide you with port data not IP information. checkout http:/ / and for some screenshots of bandwidthD and some other Linux network monitoring like iftop, and cross platform like CACTI. I would recommend bandwidthD myself as long as you can get a NIC on the monitoring computer connected between your Router and LAN, bandwidthD will create graphs and table data for you, it will use reverse DNS to try to resolve names and will break down the type of traffic to a certain extent, and it will generate html pages for you to view all this in your web browser, I run it on linux, but bandwidthD does have a windows version and it is free. However, if you use a hardware router to route your traffic from WAN to LAN you will need to connect a NIC between the LAN port on the router and wherever it actually plugs into your network (a switch likely) this can be accomplished by using port mirroring, a hub, or a tap. If for instance you use your 2003 Server as a router and your WAN and LAN are connected through it then you could monitor from that using something like Network Probe, or BandwidthD. ![]() In both cases you need to place the monitoring at a point that all traffic will flow through. Unfortunately the only really god way to accomplish what you want is with a proxy server or network monitoring applications. ![]()
