Netlink Bandwidth Monitor not updating data

My intention is to measure all traffic in 192.168.18.0 subnet mask.
This is my network, except replace 192.168.1.1 with 192.168.18.1 subnet.

So I should replace 192.168.0.0/24 with 192.168.18.0/24?

Same issue here, not all the traffic is being "captured" by nlbwmon. any idea?
The subnet has been adjusted here, 2 wifi networks, 2.4 and 5ghz via br-lan
