       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    [Toc]    [Back]

       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    [Toc]    [Back]

       -d     Change  the  default  directory  used with -R and -W options for
	      saving state information.

       -n     Don't actually take any action  that  would  effect  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  the  -d option is used.  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  the  -d option is used.  The state
	      tables are  locked  at  the  beginning  of  this	operation  and
	      unlocked once complete.

FILES    [Toc]    [Back]

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

DIAGNOSTICS    [Toc]    [Back]

       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.
