  13           Connection tracking keeps a record of what packets have passed
  14           through your machine, in order to figure out how they are related
  15           into connections.
  16
  17           This is IPv6 support on Layer 3 independent connection tracking.
  18           Layer 3 independent connection tracking is experimental scheme
  19           which generalize ip_conntrack to support other layer 3 protocols.

  29           This option adds a queue handler to the kernel for IPv6
  30           packets which enables users to receive the filtered packets
  31           with QUEUE target using libipq.
  32
  33           This option enables the old IPv6-only "ip6_queue" implementation
  34           which has been obsoleted by the new "nfnetlink_queue" code (see
  35           CONFIG_NETFILTER_NETLINK_QUEUE).

  51           ip6tables is a general, extensible packet identification framework.
  52           Currently only the packet filtering and packet mangling subsystem
  53           for IPv6 use this, but connection tracking is going to follow.
  54           Say 'Y' or 'M' here if you want to use either of those.

 154           Packet filtering defines a table `filter', which has a series of
 155           rules for simple packet filtering at local input, forwarding and
 156           local output.  See the man page for iptables(8).

 164         help
 165           The REJECT target allows a filtering rule to specify that an ICMPv6
 166           error should be issued in response to an incoming packet, rather
 167           than silently being dropped.

 175         help
 176           This option adds a `mangle' table to iptables: see the man page for
 177           iptables(8).  This table is used for various packet alterations
 178           which can effect how the packet is routed.

 185         depends on NETFILTER_ADVANCED
 186         help
 187           This option adds a `HL' target, which enables the user to decrement
 188           the hoplimit value of the IPv6 header or set it to a given (lower)
 189           value.
 190
 191           While it is safe to decrement the hoplimit value, this option also
 192           enables functionality to increment and set the hoplimit value of the
 193           IPv6 header to arbitrary values.  This is EXTREMELY DANGEROUS since
 194           you can easily create immortal packets that loop forever on the
 195           network.
 196
 197           To compile it as a module, choose M here.  If unsure, say N.

 204           This option adds a `raw' table to ip6tables. This table is the very
 205           first in the netfilter framework and hooks in at the PREROUTING
 206           and OUTPUT chains.
 207
 208           If you want to compile it as a module, say M here and read
 209           <file:Documentation/kbuild/modules.txt>.  If unsure, say `N'.
