I have a LAN with Windows 2003 domain, using Sonicwall PRO 2040, and all the internet users are created in Sonicwall (coz there is some problem in intetgrating active directory users). There are around 75 users. We have a commercial internet connection, that means, more usage than the Cap, means more money to pay.
I want to limit the usage of internet for the user, as per user per day basis, so if he exceeds 40MB a day, for the rest of the accounts get blocked.
My Sonic does give me reports of Top Users their websites, bytes downloaded etc, but that is, after the damage is done, and then running after the users make no stronger sense.
Is there any solution, to keep them away from large downloads and viewing to huge images (like email or websites)
One last, point, my dsl router is connected to the firewall directly and from firewall to the switch, so no computer is in the middle.
