Setting up a firewall with iptables on Fedora Linux is a relatively simple process. This tutorial will walk you through the steps of installing, configuring, saving, starting, and testing the firewall.
The first step is to install iptables on your Fedora Linux system. To do this, open a terminal window and type the following command:
sudo yum install iptablesThis will install the iptables package on your system.
Once iptables is installed, you can configure it to your needs. To do this, open a terminal window and type the following command:
sudo iptables -FThis will flush all existing rules from the iptables configuration. You can then add your own rules to the configuration.
Once you have configured iptables, you need to save the configuration so that it will be applied when the system is restarted. To do this, open a terminal window and type the following command:
sudo service iptables saveThis will save the current iptables configuration to the system.
Once you have saved the configuration, you need to start iptables so that it will be applied. To do this, open a terminal window and type the following command:
sudo service iptables startThis will start the iptables service and apply the configuration.
Once you have started iptables, you can test the firewall to make sure it is working correctly. To do this, open a terminal window and type the following command:
sudo iptables -LThis will list all of the rules that are currently in the iptables configuration. If the rules are correct, then the firewall is working correctly.
