NAME

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

/var/db/ipf/ipstate.ipf
/var/db/ipf/ipnat.ipf
/dev/ipl
/dev/ipstate
/dev/ipnat

DIAGNOSTICS

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.
