####Проверяем наличие правил iptables

$iptables -L | grep 'DROP       all  --  anywhere             anywhere             match-set blacklist src'

#Если нет, добавляем правило

if [ $? -ne 0 ];
then
$iptables -v -I INPUT -m set --match-set blacklist src -j DROP
fi

#Если нет, добавляем правило

$iptables -L | grep 'LOG        all  --  anywhere             anywhere             match-set blacklist src LOG level warning prefix "DROP blacklist entry"'
if [ $? -ne 0 ];
        then
        $iptables -v -I INPUT -m set --match-set blacklist src -j LOG --log-prefix "DROP blacklist entry"
fi
