cdist-type__pf_ruleset(7)
==================================
Jake Guffey <jake.guffey--@--eprotex.com>
NAME
----
cdist-type__pf_ruleset - Copy a pf(4) ruleset to $__target_host
DESCRIPTION
-----------
This type is used on *BSD systems to manage the pf firewall's ruleset.
REQUIRED PARAMETERS
-------------------
state::
Either "absent" (no ruleset at all) or "present"
OPTIONAL PARAMETERS
-------------------
source::
If supplied, use to define the ruleset to load onto the $__target_host for pf(4).
Note that this type is almost useless without a ruleset defined, but it's technically not
needed, e.g. for the case of disabling the firewall temporarily.
EXAMPLES
--------
--------------------------------------------------------------------------------
# Remove the current ruleset in place
__pf_ruleset --state absent
# Enable the firewall with the ruleset defined in $__manifest/files/pf.conf
__pf_ruleset --state present --source $__manifest/files/pf.conf
--------------------------------------------------------------------------------

--------
