Hello. I would like to know if it's possible to measure the bandwidth
usage of each computer (fixed ip numbers) with iptables. Thanks.

You can measure the number of packets and bytes sent to or from specific IP
addresses if you want. Measure the number of bytes over a known period of
time and you can work out the bandwidth.
Try something like:
iptables -A FORWARD -s a.b.c.d
iptables -A FORWARD -d a.b.c.d
iptables -L FORWARD -n -v -x
Yes, those rules have no "-j TARGET" at the end. This is correct.
Antony.
