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 ,


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 information 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 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  com-
           plete.


     -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  com-
           plete.

DIAGNOSTICS
     Arguably, the -W and -R operations should  set  the  locking
     and,  rather  than undo it, restore it to what it was previ-
     ously.


     Fragment table information is currently not saved.
