menu "IPv6: Netfilter Configuration (EXPERIMENTAL)"
depends on INET && IPV6 && NETFILTER && EXPERIMENTAL
config NF_CONNTRACK_IPV6
tristate "IPv6 support for new connection tracking (EXPERIMENTAL)"
depends on EXPERIMENTAL && NF_CONNTRACK
---help---
Connection tracking keeps a record of what packets have passed
through your machine, in order to figure out how they are related
into connections.
This is IPv6 support on Layer 3 independent connection tracking.
Layer 3 independent connection tracking is experimental scheme
which generalize ip_conntrack to support other layer 3 protocols.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_QUEUE
tristate "IP6 Userspace queueing via NETLINK (OBSOLETE)"
---help---
This option adds a queue handler to the kernel for IPv6
packets which enables users to receive the filtered packets
with QUEUE target using libipq.
THis option enables the old IPv6-only "ip6_queue" implementation
which has been obsoleted by the new "nfnetlink_queue" code (see
CONFIG_NETFILTER_NETLINK_QUEUE).

config IP6_NF_IPTABLES
tristate "IP6 tables support (required for filtering/masq/NAT)"
help
ip6tables is a general, extensible packet identification framework.
Currently only the packet filtering and packet mangling subsystem
for IPv6 use this, but connection tracking is going to follow.
Say 'Y' or 'M' here if you want to use either of those.
To compile it as a module, choose M here. If unsure, say N.
# The simple matches.
config IP6_NF_MATCH_LIMIT
tristate "limit match support"
depends on IP6_NF_IPTABLES
help
limit matching allows you to control the rate at which a rule can be
matched: mainly useful in combination with the LOG target ("LOG
target support", below) and to avoid some Denial of Service attacks.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_MAC
tristate "MAC address match support"
depends on IP6_NF_IPTABLES
help
mac matching allows you to match packets based on the source
Ethernet address of the packet.

config IP6_NF_MATCH_OPTS
tristate "Hop-by-hop and Dst opts header match support"
depends on IP6_NF_IPTABLES
help

and destination options headers of a packet.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_FRAG
tristate "Fragmentation header match support"
depends on IP6_NF_IPTABLES
help

header of the packet.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_HL
tristate "HL match support"
depends on IP6_NF_IPTABLES
help
HL matching allows you to match packets based on the hop
limit of the packet.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_MULTIPORT
tristate "Multiple port match support"
depends on IP6_NF_IPTABLES
help
Multiport matching allows you to match TCP or UDP packets based on
a series of source or destination ports: normally a rule can only
match a single range of ports.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_OWNER
tristate "Owner match support"
depends on IP6_NF_IPTABLES
help
Packet owner matching allows you to match locally-generated packets
based on who created them: the user, group, process or session.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_MARK
tristate "netfilter MARK match support"
depends on IP6_NF_IPTABLES
help
Netfilter mark matching allows you to match packets based on the
`nfmark' value in the packet. This can be set by the MARK target
(see below).
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_IPV6HEADER
tristate "IPv6 Extension Headers Match"
depends on IP6_NF_IPTABLES
help
This module allows one to match packets based upon
the ipv6 extension headers.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_AHESP
tristate "AH/ESP match support"
depends on IP6_NF_IPTABLES
help
This module allows one to match AH and ESP packets.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_LENGTH
tristate "Packet Length match support"
depends on IP6_NF_IPTABLES
help
This option allows you to match the length of a packet against a
specific value or range of values.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_EUI64
tristate "EUI64 address check"
depends on IP6_NF_IPTABLES
help
This module performs checking on the IPv6 source address
Compares the last 64 bits with the EUI64 (delivered
from the MAC address) address
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_PHYSDEV
tristate "Physdev match support"
depends on IP6_NF_IPTABLES && BRIDGE_NETFILTER
help
Physdev packet matching matches against the physical bridge ports
the IP packet arrived on or will leave by.
To compile it as a module, choose M here. If unsure, say N.
# The targets
config IP6_NF_FILTER
tristate "Packet filtering"
depends on IP6_NF_IPTABLES
help
Packet filtering defines a table `filter', which has a series of
rules for simple packet filtering at local input, forwarding and
local output. See the man page for iptables(8).
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_TARGET_LOG
tristate "LOG target support"
depends on IP6_NF_FILTER
help

any iptables table which records the packet header to the syslog.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_TARGET_REJECT
tristate "REJECT target support"
depends on IP6_NF_FILTER
help
The REJECT target allows a filtering rule to specify that an ICMPv6
error should be issued in response to an incoming packet, rather
than silently being dropped.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_TARGET_NFQUEUE
tristate "NFQUEUE Target Support"
depends on IP_NF_IPTABLES
help
This Target replaced the old obsolete QUEUE target.
As opposed to QUEUE, it supports 65535 different queues,
not just one.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MANGLE
tristate "Packet mangling"
depends on IP6_NF_IPTABLES
help
This option adds a `mangle' table to iptables: see the man page for
iptables(8). This table is used for various packet alterations
which can effect how the packet is routed.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_TARGET_MARK
tristate "MARK target support"
depends on IP6_NF_MANGLE
help
This option adds a `MARK' target, which allows you to create rules
in the `mangle' table which alter the netfilter mark (nfmark) field
associated with the packet packet prior to routing. This can change
the routing method (see `Use netfilter MARK value as routing
key') and can also be used by other subsystems to change their
behavior.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_TARGET_HL
tristate 'HL (hoplimit) target support'
depends on IP6_NF_MANGLE
help
This option adds a `HL' target, which enables the user to decrement
the hoplimit value of the IPv6 header or set it to a given (lower)
value.
While it is safe to decrement the hoplimit value, this option also
enables functionality to increment and set the hoplimit value of the
IPv6 header to arbitrary values. This is EXTREMELY DANGEROUS since
you can easily create immortal packets that loop forever on the
network.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_RAW
tristate 'raw table support (required for TRACE)'
depends on IP6_NF_IPTABLES
help
This option adds a `raw' table to ip6tables. This table is the very
first in the netfilter framework and hooks in at the PREROUTING
and OUTPUT chains.
If you want to compile it as a module, say M here and read
<file:Documentation/modules.txt>. If unsure, say `N'.
