Change Host Firewall State

Using the Networking page, Cockpit administrators can enable or disable the firewall state on the host system.

Note:

By default, the firewall management service (firewalld) is enabled on the host system. When this service is enabled, all incoming network traffic is blocked with the exception where firewall zoning rules are set to enable incoming traffic for services and their ports.

For more information about a zone-based firewall implementation and the firewall management service in Oracle Linux, see Oracle Linux 8: Configuring the Firewall or Oracle Linux 9: Configuring the Firewall.
