Can someone please explain these figures to me
-
Hi all,
I have pfSense 2.4 installed and all my LAN traffic is going via by OpenVPN Provider.
Status/Traffic Totals is showing this:-
I would of thought the WAN RX, OPT1 RX (VPN) and LAN TX would be the same values, but as you can see they are not.
Can someone please enlighten this noob as to why they are not.
TIA
Greg

A variety of things could explain different numbers.
DNS lookups from cache would show traffic on LAN but not WAN or OPT1. Any other caching you might be doing (like using Squid as a cache) can also have such an effect.
Data compression on the OpenVPN connection could also cause differences.
Depending on the media of your ISP, you could be receiving a variety of broadcast traffic on WAN. There are likely external connection attempts that are being blocked by the firewall on WAN too… those still get counted as traffic on the interface.
The numbers aren't different enough that I would think there are problems. If one interface were double the amount of the other two, then I might find reason for concern... but a difference of a couple of megabytes in an hour isn't a big deal IMHO.

Thank you. Much appreciated.
