Disable iptables

Iptables is a userspace firewall application used to configure the Linux IPv4 and IPv6 packet filtering rulesets. iptables is installed and enabled by default on Oracle Linux with a default policy and ruleset in /etc/sysconfig/iptables. iptables rules can be configured at the command line as well as with the system setup utility, i.e. "/usr/bin/setup".
 
Host firewalls, for example iptables, are a fundamental part of an information security program. If your information security program requires host firewalls, a best practice is to configure host firewalls during the last phase of the Enterprise Manager deployment.
 
iptables can be disabled by typing the following command as root.
# service iptables stop && service ip6tables stop && chkconfig iptables off && chkconfig ip6tables off
 
iptables can be re-inabled by typing the following command as root.
# service iptables start && service ip6tables start && chkconfig iptables on && chkconfig ip6tables on
