This reply says why the task failed

Application Security Task

@asingh05, iptables-save does not save the rules iptables-save is used to dump the contents of an IP Table in easily parseable format to STDOUT. Use I/O-redirection provided by your shell to write to a file. Source: https://linux.die.net/man/8/iptables-save So your rule was not permanently added. You can use a redirect on iptables-save output to /etc/sysconfig/iptables or service iptables save if you have iptables-services installed
