`dhcp`: `<boolean>` ('default =' `0`)::

Enable DHCP.

`enable`: `<boolean>` ('default =' `0`)::

Enable/disable firewall rules.

For containers the configured IP addresses will be implicitly added.

Log level for incoming traffic.

`log_level_out`: `<alert | crit | debug | emerg | err | info | nolog | notice | warning>` ::

Enable NDP (Neighbor Discovery Protocol).
