Firewall

Welcome to Firewall.

IPFW is already setup to default: Set ipfw to default accept
If you run rc-update it shows all running services, ipfw included.

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.

See: ipfw on OpenRC

Attention: Do not use FreeBSD firewall guidance.
