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

24 ---help---
25
26 This option adds a queue handler to the kernel for IPv6
27 packets which enables users to receive the filtered packets
28 with QUEUE target using libipq.
29
30 THis option enables the old IPv6-only "ip6_queue" implementation
31 which has been obsoleted by the new "nfnetlink_queue" code (see
32 CONFIG_NETFILTER_NETLINK_QUEUE).

45 help
46 ip6tables is a general, extensible packet identification framework.
47 Currently only the packet filtering and packet mangling subsystem
48 for IPv6 use this, but connection tracking is going to follow.
49 Say 'Y' or 'M' here if you want to use either of those.

95 a series of source or destination ports: normally a rule can only
96 match a single range of ports.

170 The REJECT target allows a filtering rule to specify that an ICMPv6
171 error should be issued in response to an incoming packet, rather
172 than silently being dropped.

179 help
180 This option adds a `mangle' table to iptables: see the man page for
181 iptables(8). This table is used for various packet alterations
182 which can effect how the packet is routed.

186config IP6_NF_TARGET_HL
187 tristate 'HL (hoplimit) target support'
188 depends on IP6_NF_MANGLE
189 help
190 This option adds a `HL' target, which enables the user to decrement
191 the hoplimit value of the IPv6 header or set it to a given (lower)
192 value.
193
194 While it is safe to decrement the hoplimit value, this option also
195 enables functionality to increment and set the hoplimit value of the
196 IPv6 header to arbitrary values. This is EXTREMELY DANGEROUS since
197 you can easily create immortal packets that loop forever on the
198 network.

206 This option adds a `raw' table to ip6tables. This table is the very
207 first in the netfilter framework and hooks in at the PREROUTING
208 and OUTPUT chains.

211 <file:Documentation/modules.txt>. If unsure, say `N'.
