Destination-Cache-Limit

This setting limits the number of "unanswered" destination cache entries. This number represents the number of destination addresses that do not respond during the destination cache timeout; once this number is exceeded, the firewall blocks any further new destination addresses for this interface. With the default setting (see below), this can happen if too many users on the LAN send requests to unreachable servers on the Internet.

Entering 0 as the limit globally disables the destination cache check for all interfaces. To disable the check for a particular interface, switch off the firewall on that interface. With the default setting (LAN: Firewall off // WAN: Firewall on) the device does not check the traffic of users within the LAN.

Note: The default value is set high enough to avoid triggering the IDS during normal operation.
