Firewall

Welcome to Firewall.

IPFW is already setup to default.
OpenRC manages how ipfw (/etc/init.d/ipfw) configuration is initialized.

The old way defined by TrueOS allows you to define the firewall rules via a /etc/ipfw.conf file. You have to create that file as it does not exist by default.

However, OpenRC (main branch) defines the firewall rules within the /etc/ipfw.conf file itself.

Do not use FreeBSD firewall guidance.
