To delete or flush all IPTables rules on a Linux system, including CentOS, you can use the iptables command with the -F and -X options. Here are the steps:
Open a terminal window or log in to the server using SSH.
Type the following command to delete all the rules in the filter table:
sudo iptables -F
This will flush all the rules in the filter table.
Type the following command to delete all the user-defined chains:
sudo iptables -X
This will delete all the user-defined chains.
If you have any other tables such as nat or mangle with rules that you want to delete, you can use the same command with the table name. For example:
sudo iptables -t nat -F
This will flush all the rules in the nat table.
After deleting all the rules, you can verify that the rules have been deleted by listing the rules using the following command:
sudo iptables -L
This will list the current IPTables rules. If there are no rules, you will see a message saying "Chain INPUT (policy ACCEPT)".
That's it! You have successfully deleted or flushed all IPTables rules on your Linux system.
