As an alternative - if you want a stronger reject you can run this bash
script:
if [ -f $BLACKLIST ]; then
for ipaddress in $( grep -v ^# $BLACKLIST | awk '{print $1}' ); do
iptables -v -A INPUT -s $ipaddress -j DROP
done
fi
$BLACKLIST is a lit of IP addresses or host names. This will lock out
the IPs from talking to your server entirely.
