There are a plethora of ways to do this:
You can setup rules to watch the amount of bytes going through them
using ipacct w/iptables(1), or use something else, like my favorite,
vnstat.
MRTGFE (front-end) can also calculate bandwidth from MRTG's logs,
although it will not be as accurate as using vnstat or iptables rules.
Examples provided below:
$ vnstat-eth1

Subject: track bandwith used
Hi again,
I was also wondering if anyone knows a way to track bandwith being used
through the firewall .......
I use squid as a proxy behind the firewall if that helps at all ...
Thank you again,
Peter
