Install Firestarter GUI for iptables:

sudo gedit /etc/rsyslog.d/99-fixlog.conf

*.=info;*.=notice;*.=warn;\
        auth,authpriv.none;\
        cron,daemon.none;\
        mail,news.none -/var/log/messages

sudo service rsyslog restart

To block 123.11.112.1 with iptables:

iptables -I INPUT -s 123.11.112.1 -j DROP

To enable this functionality in firestarter edit this file:

sudo gedit /etc/firestarter/user-post

Add the following line to the /etc/firestarter/user-post file:

$IPT -I INPUT -s 123.11.112.1 -j DROP

sudo service firestarter restart
