# 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'
