This guide worked for me with a few exceptions,
I additionally Ran
apt-get install xtables-addons-common xtables-addons-dkms xtables-addons-source
Once this is done, I change my default-accept policy to US Only accept.
iptables -A INPUT -m geoip –src-cc US -j ACCEPT
iptables -I INPUT -j DROP
iptables-save
Simple way to reduce the excessive Fail2Ban occurrences.
