Enable and disable firewall

The firewall is enabled by default. Disabling the firewall can be useful or even necessary in many cases, e.g. in a test environment. This step shows how to disable the firewall. Note that without a firewall, incoming and outgoing connections will no longer be scanned. Never disable the firewall permanently.

Proceed as follows:

1. Enter the command doas service pf stop in the console.
The firewall is disabled.
2. Enter the command doas service pf start in the console to re-enable the firewall.
The firewall is automatically re-enabled after each restart. This behavior is ensured by the entry pf_enable="YES" in the rc.conf file.
