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
appending 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.
