Overview
firewalld is a firewall service daemon with D-BUS interface. It is used to implement a dynamic firewall. The firewall supports network/firewall zones to define the trust level of network connections or interfaces. It has support for IPv4, IPv6 and for ethernet bridges and has a separation of runtime and permanent configuration options. It also supports an interface for services or applications to add firewall rules directly.
firewalld comes with a graphical configuration tool firewall-config. firewalld uses the iptables tool to communicate with netfilter in the kernel.
