menu "IPv6: Netfilter Configuration"
depends on INET && IPV6 && NETFILTER
config NF_CONNTRACK_IPV6
tristate "IPv6 connection tracking support"
depends on INET && IPV6 && NF_CONNTRACK
default m if NETFILTER_ADVANCED=n
---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)"
depends on INET && IPV6 && NETFILTER
depends on NETFILTER_ADVANCED
---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)"
depends on INET && IPV6
select NETFILTER_XTABLES
default m if NETFILTER_ADVANCED=n
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_RT
tristate '"rt" Routing header match support'
depends on IP6_NF_IPTABLES
depends on NETFILTER_ADVANCED
help
rt matching allows you to match packets based on the routing
header of the packet.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_OPTS
tristate '"hopbyhop" and "dst" opts header match support'
depends on IP6_NF_IPTABLES
depends on NETFILTER_ADVANCED
help
This allows one to match packets based on the hop-by-hop
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 '"frag" Fragmentation header match support'
depends on IP6_NF_IPTABLES
depends on NETFILTER_ADVANCED
help
frag matching allows you to match packets based on the fragmentation
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
depends on NETFILTER_ADVANCED
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_IPV6HEADER
tristate '"ipv6header" IPv6 Extension Headers Match'
depends on IP6_NF_IPTABLES
default m if NETFILTER_ADVANCED=n
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_AH
tristate '"ah" match support'
depends on IP6_NF_IPTABLES
depends on NETFILTER_ADVANCED
help
This module allows one to match AH packets.
To compile it as a module, choose M here. If unsure, say N.
config IP6_NF_MATCH_MH
tristate '"mh" match support'
depends on IP6_NF_IPTABLES
depends on NETFILTER_ADVANCED
help
This module allows one to match MH packets.
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
depends on NETFILTER_ADVANCED
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.
# The targets
config IP6_NF_FILTER
tristate "Packet filtering"
depends on IP6_NF_IPTABLES
default m if NETFILTER_ADVANCED=n
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
default m if NETFILTER_ADVANCED=n
help
This option adds a `LOG' target, which allows you to create rules in
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
default m if NETFILTER_ADVANCED=n
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_MANGLE
tristate "Packet mangling"
depends on IP6_NF_IPTABLES
default m if NETFILTER_ADVANCED=n
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_HL
tristate 'HL (hoplimit) target support'
depends on IP6_NF_MANGLE
depends on NETFILTER_ADVANCED
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
depends on NETFILTER_ADVANCED
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/kbuild/modules.txt>. If unsure, say `N'.
