+# Authors: Donald Yandt, Sergey G. Brester
+# 
+# Because of the rich rule commands requires firewalld-0.3.1+
+# This action uses firewalld rich-rules which gives you a cleaner iptables since it stores rules according to zones and not
+# by chain. So for an example all deny rules will be listed under <zone>_deny and all log rules under <zone>_log. 
+#
+# Also this action logs banned access attempts so you can filter that and increase ban time for offenders.
+#
+# If you use the --permanent rule you get a xml file in /etc/firewalld/zones/<zone>.xml that can be shared and parsed easliy
+#
+# This is an derivative of firewallcmd-rich-rules.conf, see there for details and other parameters.
