Which command would you use to save the current iptables rules?

The command used to save the current iptables rules is iptables-save. This command outputs the current rules in a format that can be easily restored later, making it essential for preserving firewall settings.

When you run iptables-save, it prints the active rules in the iptables configuration, allowing you to redirect this output to a file. This file can later be used with the iptables-restore command to reinstate the firewall rules, ensuring consistency and compliance with your security policies across reboots or system updates.

The other options, while seemingly similar, do not exist as valid commands in the iptables suite. Understanding the specific command for saving rules is crucial for effective firewall management in Linux systems, as it allows system administrators to set up rules that can be easily restored when needed.
