According to your signature I guess you're using Linux. The most simple
way is to create an accounting rule and to read the packet/byte counters
out of /proc/net/ipfw_chains and put it into your RRDtool archive.

I wrote a small perl script for this, along with a CGI script to watch the
stats, a perl script to create the accounting and a nice config file. I've
put all this together on a little page available under
Currently it only works with 2.2 kernels, but I'm on the way of doing
a similar thing for 2.4.

Be warned: Installation can be troubleful due to insufficient
documentation (I will do it better with the 2.4 tool!). If you have
problems with the config file (or any other), feel free to mail me.
