firewalld Configuration Tools

You can configure the firewall by using one of the following tools:

  • By using the firewall-cmd command and its several options.

  • By using the Firewall Configuration GUI

    To use this tool you must install the firewall-config package first, then start it by using the same command as the package name, for example: 

    sudo dnf install firewall-config
    sudo firewall-config &

    The command opens the configuration tool, as shown in the following figure:
