There is a limit you set in your kernel config for how many events to log on
IPFW...

If you look in your kernel config you'll probably have a line like:


options		"IPFIREWALL_VERBOSE_LIMIT=100"


If you change the '100' (or whatever it is in your case) either to a higehr
number, or '0' (which means always log) it should work OK...

I use '0' here on all our machines (remembering to clear down the log file
on a regular basis) and I've not noticed any problems...
