6 depends on INET && IPV6 && NETFILTER
12 config NF_CONNTRACK_IPV6
13 tristate "IPv6 connection tracking support"
14 depends on INET && IPV6 && NF_CONNTRACK
15 default m if NETFILTER_ADVANCED=n
18 Connection tracking keeps a record of what packets have passed
19 through your machine, in order to figure out how they are related
22 This is IPv6 support on Layer 3 independent connection tracking.
23 Layer 3 independent connection tracking is experimental scheme
24 which generalize ip_conntrack to support other layer 3 protocols.
26 To compile it as a module, choose M here. If unsure, say N.
28 config IP6_NF_IPTABLES
29 tristate "IP6 tables support (required for filtering)"
30 depends on INET && IPV6
31 select NETFILTER_XTABLES
32 default m if NETFILTER_ADVANCED=n
34 ip6tables is a general, extensible packet identification framework.
35 Currently only the packet filtering and packet mangling subsystem
36 for IPv6 use this, but connection tracking is going to follow.
37 Say 'Y' or 'M' here if you want to use either of those.
39 To compile it as a module, choose M here. If unsure, say N.

71 config IP6_NF_MATCH_OPTS
72 tristate '"hbh" hop-by-hop and "dst" opts header match support'
73 depends on NETFILTER_ADVANCED
75 This allows one to match packets based on the hop-by-hop
76 and destination options headers of a packet.
78 To compile it as a module, choose M here. If unsure, say N.
80 config IP6_NF_MATCH_HL
81 tristate '"hl" hoplimit match support'
82 depends on NETFILTER_ADVANCED
83 select NETFILTER_XT_MATCH_HL
85 This is a backwards-compat option for the user's convenience
86 (e.g. when running oldconfig). It selects
87 CONFIG_NETFILTER_XT_MATCH_HL.
89 config IP6_NF_MATCH_IPV6HEADER
90 tristate '"ipv6header" IPv6 Extension Headers Match'
91 default m if NETFILTER_ADVANCED=n
93 This module allows one to match packets based upon
94 the ipv6 extension headers.
96 To compile it as a module, choose M here. If unsure, say N.
98 config IP6_NF_MATCH_MH
99 tristate '"mh" match support'
100 depends on NETFILTER_ADVANCED
102 This module allows one to match MH packets.
104 To compile it as a module, choose M here. If unsure, say N.
106 config IP6_NF_MATCH_RPFILTER
107 tristate '"rpfilter" reverse path filter match support'
108 depends on NETFILTER_ADVANCED
110 This option allows you to match packets whose replies would
111 go out via the interface the packet came in.
113 To compile it as a module, choose M here. If unsure, say N.
114 The module will be called ip6t_rpfilter.
116 config IP6_NF_MATCH_RT
117 tristate '"rt" Routing header match support'
118 depends on NETFILTER_ADVANCED
120 rt matching allows you to match packets based on the routing
121 header of the packet.
123 To compile it as a module, choose M here. If unsure, say N.
126 config IP6_NF_TARGET_HL
127 tristate '"HL" hoplimit target support'
128 depends on NETFILTER_ADVANCED && IP6_NF_MANGLE
129 select NETFILTER_XT_TARGET_HL
131 This is a backwards-compatible option for the user's convenience
132 (e.g. when running oldconfig). It selects
133 CONFIG_NETFILTER_XT_TARGET_HL.
136 tristate "Packet filtering"
137 default m if NETFILTER_ADVANCED=n
139 Packet filtering defines a table `filter', which has a series of
140 rules for simple packet filtering at local input, forwarding and
141 local output. See the man page for iptables(8).
143 To compile it as a module, choose M here. If unsure, say N.
145 config IP6_NF_TARGET_REJECT
146 tristate "REJECT target support"
147 depends on IP6_NF_FILTER
148 default m if NETFILTER_ADVANCED=n
150 The REJECT target allows a filtering rule to specify that an ICMPv6
151 error should be issued in response to an incoming packet, rather
152 than silently being dropped.
154 To compile it as a module, choose M here. If unsure, say N.
157 tristate "Packet mangling"
158 default m if NETFILTER_ADVANCED=n
160 This option adds a `mangle' table to iptables: see the man page for
161 iptables(8). This table is used for various packet alterations
162 which can effect how the packet is routed.
164 To compile it as a module, choose M here. If unsure, say N.
167 tristate 'raw table support (required for TRACE)'
169 This option adds a `raw' table to ip6tables. This table is the very
170 first in the netfilter framework and hooks in at the PREROUTING
173 If you want to compile it as a module, say M here and read
174 <file:Documentation/kbuild/modules.txt>. If unsure, say `N'.
176 # security table for MAC policy
177 config IP6_NF_SECURITY
178 tristate "Security table"
180 depends on NETFILTER_ADVANCED
182 This option adds a `security' table to iptables, for use
183 with Mandatory Access Control (MAC) policy.
189 depends on NF_CONNTRACK_IPV6
190 depends on NETFILTER_ADVANCED
193 The IPv6 NAT option allows masquerading, port forwarding and other
194 forms of full Network Address Port Translation. It is controlled by
195 the `nat' table in ip6tables, see the man page for ip6tables(8).
197 To compile it as a module, choose M here. If unsure, say N.
201 config IP6_NF_TARGET_MASQUERADE
202 tristate "MASQUERADE target support"
204 Masquerading is a special case of NAT: all outgoing connections are
205 changed to seem to come from a particular interface's address, and
206 if the interface goes down, those connections are lost. This is
207 only useful for dialup accounts with dynamic IP address (ie. your IP
208 address will be different on next dialup).
210 To compile it as a module, choose M here. If unsure, say N.
212 config IP6_NF_TARGET_NPT
213 tristate "NPT (Network Prefix translation) target support"
215 This option adds the `SNPT' and `DNPT' target, which perform
216 stateless IPv6-to-IPv6 Network Prefix Translation per RFC 6296.
218 To compile it as a module, choose M here. If unsure, say N.
