Data Usage

I would like to know why I am seeing a difference in data usage each month. My data cycle restarts on the 18th. I clear my counters on my firewall on the 18th. At the time I do this there may have been a few MB of data used, which will not be enough to skew the situation here. So, last month, Cox stated I used 95% of my data, which I understand is both ingress and egress. The counters on my firewall show a max of 200GiB total (ingress/egress). So, I am interested to understand where all this extra data was used. I know I had downloaded a lot from services like OneDrive and GoogleDrive, but nowhere near a TB of data. I have witnessed over the past two months.

I have Cox Fiber and my internet connection goes directly into my personal firewall, then all my devices are connected to switches and AP's and to be clear, I am looking at the WAN interface on the firewall, because obviously, that is the only interface that matters.

For this month so far, Cox says I have used 71GB, but I am seeing I have only used 12.54GiB ingress and 3.77GiB egress data. Sorry, but 13 + 4 != 71

Thanks,

    Your not monitoring all data, unless your personal firewall is between the modem and ALL devices in home using internet, as well as measuring ALL packets. My Router measures all data passing, and it is always within a mb of data as Cox says I have used. Firewalls typically measure less data than a router because they focus on security and filtering, and do not always see everything properly.
