Yes this is true.

Yes, it is useful. Especially on Windows or other OS that gets attacked
and you have no Firewall. This is why I recommend people use a separate
HW Firewall. Unless they are running Linux *AND* know how to configure a

There are two options on 3 here
A suitably configured native firewall or separate CentOS or OpenWRT
could be a solution too.

Packets can have varying amount of payload.
*Network traffic* is data in a network. In computer networks, the data
is encapsulated in packets.
However I'm not entirely sure what OpenWRT statistics relate to.
but I have a link to the last 24 hrs.
You can see that while the "packets" received remain at over 30%
overnight there is no associated traffic.
Perhaps what OpenWRT is "measuring" as Packets are infact connection
No-one gets charged for "packets" but you get charged for "traffic".
My ISPs traffic Monitor totals and graphs over last 24hrs / last 7 days/
last 30 days closely agrees with my OpenWRT monitor.
