Sh NAME
Nm pf.boot.conf
Nd initial configuration for packet filter
Sh DESCRIPTION
The
Nm
file is used as initial configuration for the
Xr pf 4
packet filter.
This file is loaded before the network is configured by the
Xr rc.d 8
script
Em network .
Its purpose is to protect the machine from possible attacks between
the network configuration and the loading of the final ruleset.
Pp
The syntax of this file is described in
Xr pf.conf 5 .
Pp
Note that at the stage the configuration is loaded, the network
interface(s) do not have an IP address yet, so you
Em cannot
use rules that derive addresses from an interface (for example:
Dq pass out from any to fxp0 ) .
Sh FILES
Bl -tag -width "/etc/defaults/pf.boot.conf" -compact
It Pa /etc/defaults/pf.boot.conf
Default initial ruleset file.
It Pa /etc/pf.boot.conf
Override of the default initial ruleset file.
El
Sh EXAMPLES
When using NFS (e.g. diskless situations), you'll also need the following
rules in addition to the default rules to unblock NFS:
Bd -literal -offset indent
scrub in all no-df
pass in proto udp from any port { 111, 2049 } to any
pass out proto udp from any to any port { 111, 2049 }
