I am trying to find a way to monitor how much Bandwidth is being used on our Primary Internet Connection by certain services.
Our setup includes an SBS 2011 server using Exchange 2010 (OA and OWA) and a CRM package that users sync with every evening over VPN (PPTP). These are the two main services that run on the server and are accessed by all internal and external users. I am trying to find out how much bandwidth is used by each of these services (Exchange OA/ OWA and the VPN Sync). Our perimeter device is a CheckPoint UTM-1 Edge NW.
The idea of this is to determine which services use more bandwidth and then use the QoS on the Firewall to prioities traffic. I was looking at the ntopng (http://www.ntop.org/products/ntop/
tool which seems to be capable of what I want to do.
If anyone has any suggestions it would be be a big help.
