firewalld (Dynamic Firewall Manager) provides a dynamically managed firewall with
support for network/firewall “zones” to assign a level of trust to a network and its
associated connections, interfaces or sources. It has support for IPv4, IPv6, Ethernet
bridges and also for IPSet firewall settings. There is a separation of the runtime and
permanent configuration options.
The firewalld package can be removed with the following command:
$ sudo zypper remove firewalld
