Traffic Graphs Do Not Add Up
-
Hey Gang,
We have been looking at the traffic graphs, and the totals do not add up.
For example, our WAN interface is showing inbound traffic of for example 100/mbps, but if we look at the inbound traffic on all of the other interfaces, it adds to up around 30.
Do you think this excess traffic is simply stuff trying to attack us but getting rejected by the firewall? Seems pretty high? What else could it be?

@UnjustCactus Package ntopng can give you a nice breakout of all the traffic. Is a bit heavy on resources though.

Does it come and go, or remain constant?
I'm having a problem which sounds similar, but it comes and goes. Specifically, while I have user activity on my network everything looks pretty normal, but after user activity stops, the bandwidth usage on my WAN port increases significantly, while my other (interior) ports remain idle. Once user activity resumes, the excess load continues for a little while, then vanishes. Maybe this is unrelated, but I just thought I'd ask.
Here is the thread for mine: https://forum.netgate.com/topic/155591/pfsense-using-unreasonable-amount-of-bandwidth-while-idle/66
