Linux Disable / Remove The Iptables Firewall

Q. How do I disable the iptables firewall in Fedora Core Linux?

A. Iptables is used to set up, maintain, and inspect the tables of IP packet filter rules in the Linux kernel.

If you are using RHEL (Redhat), Fedora core or Cent os Linux just type following commands to disable the iptables firewall:
# service iptables save
# service iptables stop
# chkconfig iptables off

If you are using any other Linux distribution type the following command to clear up firewall rules:
# iptables -F
# iptables -X
# iptables -t nat -F
# iptables -t nat -X
# iptables -t mangle -F
# iptables -t mangle -X
# iptables -P INPUT ACCEPT
# iptables -P OUTPUT ACCEPT

You may need to put above rules in a shell script and execute the same. Also remove your iptables startup script from your network configuration file such as /etc/network/interfaces. Look for post-up directive.

    Simple and useful article! Now I understand how to disable iptables :-)… How is it possible to disable iptables in other distributions? Does the “service iptables stop” command work?

    thanks

    It seems not that effective. When I restart server iptables will be up again!

    Can I just de-install (remove) iptables ?
