# Fail2Ban configuration file## Author: Donald Yandt## 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## Example commands to view rules:# firewall-cmd [--zone=<zone>] --list-rich-rules# firewall-cmd [--zone=<zone>] --list-all# firewall-cmd [--zone=zone] --query-rich-rule='rule'[Definition]actionstart =actionstop =actioncheck =# you can also use zones and/or service names.## zone example:# firewall-cmd --zone=<zone> --add-rich-rule="rule family='ipv4' source address='<ip>' port port='<port>' protocol='<protocol>' log prefix='f2b-<name>' level='<level>' limit value='<rate>/m' <blocktype>"# service name example:# firewall-cmd --zone=<zone> --add-rich-rule="rule family='ipv4' source address='<ip>' service name='<service>' log prefix='f2b-<name>' level='<level>' limit value='<rate>/m' <blocktype>"# Because rich rules can only handle single or a range of ports we must split ports and execute the command for each port.
