PFILCTL(8)		FreeBSD	System Manager's Manual		    PFILCTL(8)

NAME
     pfilctl --	pfil(9)	control	utility

SYNOPSIS
     pfilctl heads
     pfilctl hooks
     pfilctl link <-i |	-o> [-a] hook head
     pfilctl unlink <-i	| -o> hook head

DESCRIPTION
     The pfilctl utility is intended to	view and change	configuration of the
     pfil(9) packet filtering hooks and	filters	on them.

COMMANDS
     heads   List available packet filtering points.

     hooks   List available packet filters.

     link <-i |	-o> [-a] hook head
	     Link hook to head.	 With the -i flag the hook will	be connected
	     as	input and with -o as output hook.  At least one	of -i or -o is
	     required.	By default pfilctl will	prepend	the hook in front of
	     other hooks if any	present: new hook will be as close to the wire
	     as	possible, so that on input it will be the first	filter and on
	     output it will be the last.  Adding the -a	flag switches to ap-
	     pending new hook instead of prepending.

     unlink <-i	| -o> hook head
	     Unlink hook on head.  At least one	of -i or -o is required.  With
	     the -i flag the hook will be removed from the input list of hooks
	     and with -o on output list.
