firewalld supports IPv6 in addition to IPv4 and can manage separate firewall zones with different levels of trust are defined in zone profiles. With the help of the NetworkManager, the appropriate zone profiles can be activated automatically when connecting to known WiFi or Ethernet networks via firewalld. Applications such as firewall-config or firewall-applet provide graphical frontends for mouse-oriented administrators.
