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 experi-
       ence  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  informa-
	      tion.

       -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 com-
	      plete.

       -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

SEE ALSO
       ipf(8), ipl(4), ipmon(8), ipnat(8)

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.
