No offense, but you can't have looked too hard. There's a section in
ipfw(8) titled ``SYSCTL VARIABLES'' which documents all the sysctls in
the net.inet.ip.fw tree. Here's an excerpt:
SYSCTL VARIABLES
A set of sysctl(8) variables controls the behaviour of the firewall.
These are shown below together with their default value and meaning:
net.inet.ip.fw.debug: 1
Controls debugging messages produced by ipfw.
net.inet.ip.fw.one_pass: 1
[...]
net.inet.ip.fw.dyn_buckets: 256
net.inet.ip.fw.curr_dyn_buckets: 256
The configured and current size of the hash table used to hold
dynamic rules. This must be a power of 2. The table can only be
resized when empty, so in order to resize it on the fly you will
probably have to flush and reload the ruleset.
