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

       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 previously.

       Fragment table information is currently not saved.
