I upgraded from 2.x to 3.x ages ago but haven't had call to change the firewall settings.
Now i needed to add a change, when i tried to apply i get the message below.
Firewall rules causing the problem is
DIRECTION: INPUT
ACTION: LOG
EXTRA OPTIONS: -m limit --limit 12/min --log-prefix 'IP INPUT drop: '

Error received is
