Packet dropping and counting

[Shaiful]

Hi,

I have two related questions:

1)How can we effectively measure packet drop by the
router or firewall?

2)How can we conveniently measure packet count
forwarded by the router or firewall?

Assuming that we have root access to the router and
firewall.

Thanks in advance,

Regards,
Shaiful
