Hi i am new to the forum but i will get straight down to the point, i downloaded UNTANGLE software configured and has been live now for a couple of months. We use this to do various blocking of sites etc. My problem is when i get reports at the end of the month i usually go through and do a quick check etc and i usually compare it with our ISP bills BUT they tend to vary from what our ISP CISCO routers are recording and i mean a huge difference. Can someone enlighten me on why this is please????
