The 'destination cache timeout' specifies how long the device remembers the path to a destination address when no packets are sent to it.
This value also influences the length of time the device takes to change the settings of the firewall: It accepts state changes after at least half of the 'destination cache timeout' time, on average after one quarter of the timeout. Thus with the default setting of 30 seconds, changes to the firewall come into effect on average after 7.5 seconds, but no later than after 15 seconds.
