To disable iptables on a Red Hat server, you can use this command to save the current rules first:
[email protected] [/]# /etc/init.d/iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
Then, this command turns off the firewall
[email protected] [/]# /etc/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: nat mangle filte[ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
You can also use this command to disable it when the server boots.
[email protected] [/]# chkconfig iptables off
