SYNOPSISipfs [-nv] -l
ipfs [-nv] -u
ipfs [-nv] [-d dirname] -R

ipfs [-nNSv] -f filename -i <if1>,<if2>
DESCRIPTION
The ipfs utility enables the saving of state information across
reboots. Specifically, the utility allows state information created for
NAT entries and rules using "keep state" to be locked (modification
prevented) and then saved to disk. Then, after a reboot, that informa‐
tion is restored. The result of this state-saving is that connections
are not interrupted.
OPTIONS
The following options are supported:
-d Change the default directory used with -R and -W options for sav‐
ing state information.
-n Do not take any action that would affect information stored in
the kernel or on disk.
-v Provides a verbose description of ipfs activities.
-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.
This directory can be changed with 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.
This directory can be changed with the -d option. The state
tables are locked at the beginning of this operation and unlocked
once complete.

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