In order to block a whole country by CIDR range, first you will need to obtain that information. It is available in the list below.

To apply this info to APF, simply copy the link and then in the CLI on the server:

wget <link>
cat *.zone >> /etc/apf/deny_hosts.rules
/etc/init.d/apf restart

That should add the CIDR range for that country to the deny list.
