Please how one can configure DDoS deflate to deny low volume attacks?

======================

Installing DDoS Deflate:

Probably worth using improved version of DDoS deflate here: https://github.com/phoenixweb/ddos-deflate/
Following tutorial is for the original version with lower number of features.
----

wget http://www.inetbase.com/scripts/ddos/install.sh;chmod 0700 install.sh;./install.sh

Then whitelist your IP or other important IP that should be ignored and that can produce many connections like a FTP (example IP: 127.0.0.1). Just add one IP per line:
vi /usr/local/ddos/ignore.ip.list
LEGEND fo "vi" editor: "a" = start editing; "Ctrl+C" stop editing; ":wq" save changes and quit; ":q!" dont save and quit

Then open deflate file:
vi /usr/local/ddos/ddos.sh;


replace:
netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -nr > $BAD_IP_LIST
by:
netstat -ntu | grep ':' | awk '{print $5}' | sed 's/::ffff://' | cut -f1 -d ':' | sort | uniq -c | sort -nr > $BAD_IP_LIST
below line:
echo "$CURR_LINE_IP with $CURR_LINE_CONN connections" >> $BANNED_IP_MAIL
add following new line:
echo -e "\nhttps://www.abuseipdb.com/check/$CURR_LINE_IP\nhttps://www.badips.com/info/$CURR_LINE_IP\nhttps://myip.ms/info/whois/$CURR_LINE_IP\n\n $(/usr/bin/whois $CURR_LINE_IP|grep -iv whois)" >> $BANNED_IP_MAIL
(so the e-mail contains some more useful details about the banned IP)

then open deflate conf. file:
vi /usr/local/ddos/ddos.conf
change:
APF_BAN=1

to:
APF_BAN=0

Uninstalling DDoS deflate:
wget http://www.inetbase.com/scripts/ddos/uninstall.ddos;chmod 0700 uninstall.ddos;./uninstall.ddos

Please do you have any suggestions to this configuration or how do you do it?
