Hi,
I've just got a dual NIC from Amazon: https://www.amazon.com/gp/product/B09D3JL14S?ref=ppx_pt2_dt_b_prod_image
It works great with OpnSense as one of the reviews suggested although VnStat fails to display any stats for it while for the other 2 cards it continues to work as expected. See attached screenshots of both cases.
I'd appreciate any ideas.
Never mind. Apparently after adding a NIC one has to reset VnStat DB, there's a button in General tab.
