Today after configuring ipfw , i kept receiving this message:
ipfw: install_state: Too many dynamic rules
After a little googling i found out the problem.
Problem solved after i change following sysctl value:
# sysctl net.inet.ip.fw.dyn_max=16384
You can also permanently add it in your sysctl.conf file so it is setup after reboot:
# echo “sysctl net.inet.ip.fw.dyn_max=16384″ >> /etc/sysctl.conf
The default value is 4096.
