Flush Connection Reload:
When this option is enabled, and a rewall con guration change is made, existing connections that had been
permitted by the previous rewall rules will be terminated. That way if the new rewall rules can't permit a connection that had been previously
established, it will be terminated and won't be able to reconnect. When this option is disabled, existing connections are allowed to continue until
they do timeout, even if the new rules wouldn't allow these connections to be established.
