Redhat : IPTABLES : How to persist iptables as its changes are not saved by default

https://www.geeksforgeeks.org/iptables-restore-command-in-linux-with-examples/

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/4/html/security_guide/s2-firewall-ipt-act-sav

7.2.2. SAVING AND RESTORING IPTABLES RULES

Firewall rules are only valid for the time the computer is on; so, if the system is rebooted, the rules are automatically flushed and reset. To save the rules so that they are loaded later, use the following command:

/sbin/service iptables save

The rules are stored in the file /etc/sysconfig/iptables and are applied whenever the service is started or restarted, including when the machine is rebooted.

The EFS mount helper is part of the amazon-efs-utils package. The amazon-efs-utils package is an open-source collection of Amazon EFS tools. For more information, see Manually installing the Amazon EFS client.

Before the Amazon EFS mount helper was available, we recommended mounting your Amazon EFS file systems using the standard Linux NFS client. For more information, see Mounting file systems without the EFS mount helper.
