You can use the following commands to start/restart/stop iptables on your Linux server:
To start iptables:
service iptables start
To stop iptables:
service iptables stop
To restart iptables:
service iptables restart
You can determine whether iptables is running or not using following command:
service iptables status
If “service” command doesn’t work, you can use the following command
/etc/init.d/iptables start/stop/restart
You can also configured iptables to start automatically on boot. You will need to use chkconfig command to turn it on:
chkconfig iptables on
To use above commands, you will need the root access of your server.
