iptables: Restore iptables configuration from a file.

iptables-restore

$ sudo iptables-restore < ${path-to-iptables_file}

try on your machine

This command is used to restore the iptables rules from a specified file. Here's a breakdown of the command:

sudo: It is used to execute the command with superuser privileges. This is required because modifying iptables rules typically requires administrative permissions.
iptables-restore: It is the command used to restore the iptables rules from a file. It reads the rules from the specified file and applies them to the iptables configuration.
<: It is a redirection operator used to redirect the contents of a file to the command. In this case, it takes the content of the iptables file and feeds it to the iptables-restore command.
${path-to-iptables_file}: It is a placeholder for the actual path to the iptables file. You need to replace it with the specific path of the file you want to restore the rules from.

So, when you run this command and provide the correct path to the iptables file, it will restore the rules specified in that file to the iptables configuration.
