Hi. Our team does not have any direct access to your droplet’s internals once you’ve created the droplet. We do not make any changes within any users droplets apart from the root password reset tool which is fully automated.

iptables does not save records automatically on reboot. You can find more details as well as an example of how to implement automatic loading of your rules on boot here.

The iptables “save” function must be accompanied by an iptables “restore” on boot.
