This port was just too cool to not post about. Edwin Groothuis has created ipfw-graph which will graph the usage of the rules in your IPFW ruleset on FreeBSD:



Displays a graphical overview of bytes going through your IPFW
rules and a piled overview of the percentage on which rule it
passed.

FreeBSD only, GTK required.
