I want to have a system running on windows to monitor users bandwith and capping the on say 3gb usage per month. Im new to this and really need help?

Dear,

For me i monitor my client via inbox .

I monitor the via Winbox as well, but would like to automate the process. I tried using Antamedia's Bandwidth Manager, but it wont see my clients ip's, it only see the router in my office ip. Is there a way to get the client's ip adresses trough to the server?
