| 29 | The <application>firewalld</application> package provides a dynamically
|
---|
| 30 | managed firewall with support for network or firewall zones to define the
|
---|
| 31 | trust level of network connections or interfaces. It has support for
|
---|
| 32 | IPv4, IPv6 firewall settings and for ethernet bridges and a separation of
|
---|
| 33 | runtime and permanent configuration options. It also provides an
|
---|
| 34 | interface for services or applications to add nftables or iptables and
|
---|
| 35 | ebtables rules directly.
