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 
SW firewall.

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 
attempts?

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.
