# Author: Edgar Hoch
# Copied from iptables-new.conf and modified for use with firewalld by Edgar Hoch.
# It uses "firewall-cmd" instead of "iptables".
# firewall-cmd is based on the command of version firewalld-0.3.4-1.fc19.
#
# Because of the --remove-rules in stop this action requires firewalld-0.3.8+
