How To Start iptables
You can start, stop, and restart iptables after booting by using the commands:
# service iptables start
# service iptables stop
# service iptables restart
To get iptables configured to start at boot, use the chkconfig command:.
# chkconfig iptables on
Determining The Status of iptables
# service iptables status
Firewall is stopped.
How to backup running iptables scripts
This example exports the iptables-save output to a text file named firewall-config.
# iptables-save > firewall-config
After editing the firewall-config file with the commands you need, you can reload it into the active firewall rule set with the iptables-restore command.
# iptables-restore < firewall-config
Finally, you should permanently save the active configuration so that it will be loaded automatically when the system reboots:
# service iptables save
If desired, you can eventually convert this firewall-config file into a regular iptables script so that it becomes more easily recognizable and manageable.
