PFS(8) BSD System Manager's Manual PFS(8)NAME
pfs -- save and restore information for NAT and state tables
SYNOPSIS
pfs [-v] -l
pfs [-bv] -R filename
pfs [-bv] -r filename
pfs [-v] -u
pfs [-bv] -W filename
pfs [-bv] -w filename
DESCRIPTION
The pfs command allows state information created for NAT entries and rules using ``keep state'' to be locked (modification prevented) and
then saved to disk, allowing for the system to experience a reboot, followed by the restoration of that information, resulting in connections
not being interrupted.
OPTIONS -b The information are read or stored using binary format. The default format is a readable ASCII format, similar to pfctl.conf
syntax.
-l Lock state tables in the kernel.
-R filename Restore information from filename and load it into the kernel. The state tables are locked at the beginning of this operation
and unlocked once complete.
-r filename Read information in from filename and load it into the kernel. This requires the state tables to have already been locked and
does not change the lock once complete.
-u Unlock state tables in the kernel.
-v Provide a verbose description of what's being done.
-W filename Write information from the kernel out to filename. The state tables are locked at the beginning of this operation and
unlocked once complete.
-w filename Write information from the kernel out to filename. This requires the state tables to have already been locked and does not
change the lock once complete.

ipfs - saves and restores information for NAT and state tables.
SYNOPSIS
ipfs [-nv] -l
ipfs [-nv] -u
ipfs [-nv] [ -d <dirname> ] -R
ipfs [-nv] [ -d <dirname> ] -W
ipfs [-nNSv] [ -f <filename> ] -r
ipfs [-nNSv] [ -f <filename> ] -w
ipfs [-nNSv] -f <filename> -i <if1>,<if2>
DESCRIPTION
ipfs allows state information created for NAT entries and rules using keep state to be locked (modification prevented) and then saved to
disk, allowing for the system to experience a reboot, followed by the restoration of that information, resulting in connections not being
interrupted.
OPTIONS -d Change the default directory used with -R and -W options for saving state information.
-n Don't actually take any action that would affect information stored in the kernel or on disk.
-v Provides a verbose description of what's being done.
-i <ifname1>,<ifname2>
Change all instances of interface name ifname1 in the state save file to ifname2. Useful if you're restoring state information
after a hardware reconfiguration or change.
-N Operate on NAT information.
-S Operate on filtering state information.
-u Unlock state tables in the kernel.
-l Lock state tables in the kernel.
-r Read information in from the specified file and load it into the kernel. This requires the state tables to have already been locked
and does not change the lock once complete.
-w Write information out to the specified file and from the kernel. This requires the state tables to have already been locked and
does not change the lock once complete.
-R Restores all saved state information, if any, from two files, ipstate.ipf and ipnat.ipf, stored in the /var/db/ipf directory unless
otherwise specified by the -d option. The state tables are locked at the beginning of this operation and unlocked once complete.
-W Saves in-kernel state information, if any, out to two files, ipstate.ipf and ipnat.ipf, stored in the /var/db/ipf directory unless
otherwise specified by the -d option. The state tables are locked at the beginning of this operation and unlocked once complete.
FILES

Perhaps the -W and -R operations should set the locking but rather than undo it, restore it to what it was previously. Fragment table
information is currently not saved.
