We have two routers that terminate our Internet connections. Each router also has two Ethernet connection -- one towards the corporate environment and one towards the ASP side.
I need to be able to report on how much of the Internet bandwidth that the ASP side is using. Note that traffic can go from any interface to any other interface, so measuring the flows on the Ethernet facing the ASP won't give the desired result.
Can anyone point to a URL or instruction on how to do that?
