I have a network with around 120 components (workstation, servers, routers - use to create VPN between office location) I want to create trafiic report for all components (filter by ip, destination ip, used protocol, used software). I want to be able to see who generate traffic on my network and also what type of software use: torrent, dc++, streaming .... I can't use proxy server because I have mutiple location and each location have own gateway for internet.
Can someone tell me one or more solution (if is possible free) to rich this objective, if is need to instal a client on workstation is okay but is important to use one server to report network traffic.
I try to use demo version from SolarWinds but I can't set up. We have linksys router between offices.
Thanks for any suggestions
