NAME
     pfs -- save and restore information for NAT and state tables

SYNOPSIS
     pfs [-v] -l
     pfs [-bv] -R filename
     pfs [-bv] -r filename
     pfs [-v] -u
     pfs [-bv] -W filename
     pfs [-bv] -w filename

DESCRIPTION
     The pfs command 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 sys-
     tem to experience a reboot, followed by the restoration of that information, resulting in
     connections not being interrupted.

OPTIONS
     -b 	    The information are read or stored using binary format.  The default format
		    is a readable ASCII format, similar to pfctl.conf syntax.

     -l 	    Lock state tables in the kernel.

     -R filename    Restore information from filename and load it into the kernel.  The state
		    tables are locked at the beginning of this operation and unlocked once com-
		    plete.

     -r filename    Read information in from filename and load it into the kernel.  This requires
		    the state tables to have already been locked and does not change the lock
		    once complete.

     -u 	    Unlock state tables in the kernel.

     -v 	    Provide a verbose description of what's being done.

     -W filename    Write information from the kernel out to filename.	The state tables are
		    locked at the beginning of this operation and unlocked once complete.

     -w filename    Write information from the kernel out to filename.	This requires the state
		    tables to have already been locked and does not change the lock once com-
		    plete.
