If unsure, say N.config IP6_NF_IPTABLES	tristate "IP6 tables support (required for filtering/masq/NAT)"	help	  ip6tables is a general, extensible packet identification framework.

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.

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.#  dep_tristate '  MAC address match support' CONFIG_IP6_NF_MATCH_MAC $CONFIG_IP6_NF_IPTABLESconfig 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.

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	  This option adds a `LOG' target, which allows you to create rules in	  any iptables table which records the packet header to the syslog.

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.

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.

This table is the very	  first in the netfilter framework and hooks in at the PREROUTING	  and OUTPUT chains.
