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
information is restored. The result of this state-saving is that connections
are not interrupted.
The following options are supported:
-d
Change the default directory used with -R and
-W options for saving 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.
-z zonename
Operate on the in-zone state information for the
specified zone. If neither this option nor
-G is specified, the current
zone is used. This command is only available in the Global Zone. See
ZONES in
ipf(8) for more information.
-G zonename
Operate on the global zone controlled state information
for the specified zone. If neither this option nor
-z is specified, the
current zone is used. This command is only available in the Global Zone. See
ZONES in
ipf(8) for more information.

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.
