To save your changes to the firewall rules so that they are
loaded when the iptables
service next
starts, use the following command:
# /sbin/iptables-save /etc/sysconfig/iptables
The command saves the rules to
/etc/sysconfig/iptables
. For IPv6, you can
use /sbin/ip6tables-save >
/etc/sysconfig/ip6tables to save the rules to
/etc/sysconfig/ip6tables
.
