8 config NF_CONNTRACK_IPV6
9 tristate "IPv6 connection tracking support"
10 depends on INET && IPV6 && NF_CONNTRACK
11 default m if NETFILTER_ADVANCED=n
13 Connection tracking keeps a record of what packets have passed
14 through your machine, in order to figure out how they are related
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.
21 To compile it as a module, choose M here. If unsure, say N.
24 tristate "IP6 Userspace queueing via NETLINK (OBSOLETE)"
25 depends on INET && IPV6 && NETFILTER
26 depends on NETFILTER_ADVANCED
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.
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).

46 tristate "IP6 tables support (required for filtering)"
47 depends on INET && IPV6
48 select NETFILTER_XTABLES
49 default m if NETFILTER_ADVANCED=n
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.
56 To compile it as a module, choose M here. If unsure, say N.
61 config IP6_NF_MATCH_AH
62 tristate '"ah" match support'
63 depends on NETFILTER_ADVANCED
65 This module allows one to match AH packets.
67 To compile it as a module, choose M here. If unsure, say N.
69 config IP6_NF_MATCH_EUI64
70 tristate '"eui64" address check'
71 depends on NETFILTER_ADVANCED
73 This module performs checking on the IPv6 source address
74 Compares the last 64 bits with the EUI64 (delivered
75 from the MAC address) address
77 To compile it as a module, choose M here. If unsure, say N.
79 config IP6_NF_MATCH_FRAG
80 tristate '"frag" Fragmentation header match support'
81 depends on NETFILTER_ADVANCED
83 frag matching allows you to match packets based on the fragmentation
86 To compile it as a module, choose M here. If unsure, say N.
88 config IP6_NF_MATCH_OPTS
89 tristate '"hbh" hop-by-hop and "dst" opts header match support'
90 depends on NETFILTER_ADVANCED
92 This allows one to match packets based on the hop-by-hop
93 and destination options headers of a packet.
95 To compile it as a module, choose M here. If unsure, say N.
97 config IP6_NF_MATCH_HL
98 tristate '"hl" match support'
99 depends on NETFILTER_ADVANCED
101 HL matching allows you to match packets based on the hop
104 To compile it as a module, choose M here. If unsure, say N.
106 config IP6_NF_MATCH_IPV6HEADER
107 tristate '"ipv6header" IPv6 Extension Headers Match'
108 default m if NETFILTER_ADVANCED=n
110 This module allows one to match packets based upon
111 the ipv6 extension headers.
113 To compile it as a module, choose M here. If unsure, say N.
115 config IP6_NF_MATCH_MH
116 tristate '"mh" match support'
117 depends on NETFILTER_ADVANCED
119 This module allows one to match MH packets.
121 To compile it as a module, choose M here. If unsure, say N.
123 config IP6_NF_MATCH_RT
124 tristate '"rt" Routing header match support'
125 depends on NETFILTER_ADVANCED
127 rt matching allows you to match packets based on the routing
128 header of the packet.
130 To compile it as a module, choose M here. If unsure, say N.
133 config IP6_NF_TARGET_LOG
134 tristate "LOG target support"
135 default m if NETFILTER_ADVANCED=n
137 This option adds a `LOG' target, which allows you to create rules in
138 any iptables table which records the packet header to the syslog.
140 To compile it as a module, choose M here. If unsure, say N.
143 tristate "Packet filtering"
144 default m if NETFILTER_ADVANCED=n
146 Packet filtering defines a table `filter', which has a series of
147 rules for simple packet filtering at local input, forwarding and
148 local output. See the man page for iptables(8).
150 To compile it as a module, choose M here. If unsure, say N.
152 config IP6_NF_TARGET_REJECT
153 tristate "REJECT target support"
154 depends on IP6_NF_FILTER
155 default m if NETFILTER_ADVANCED=n
157 The REJECT target allows a filtering rule to specify that an ICMPv6
158 error should be issued in response to an incoming packet, rather
159 than silently being dropped.
161 To compile it as a module, choose M here. If unsure, say N.
164 tristate "Packet mangling"
165 default m if NETFILTER_ADVANCED=n
167 This option adds a `mangle' table to iptables: see the man page for
168 iptables(8). This table is used for various packet alterations
169 which can effect how the packet is routed.
171 To compile it as a module, choose M here. If unsure, say N.
173 config IP6_NF_TARGET_HL
174 tristate 'HL (hoplimit) target support'
175 depends on IP6_NF_MANGLE
176 depends on NETFILTER_ADVANCED
178 This option adds a `HL' target, which enables the user to decrement
179 the hoplimit value of the IPv6 header or set it to a given (lower)
182 While it is safe to decrement the hoplimit value, this option also
183 enables functionality to increment and set the hoplimit value of the
184 IPv6 header to arbitrary values. This is EXTREMELY DANGEROUS since
185 you can easily create immortal packets that loop forever on the
188 To compile it as a module, choose M here. If unsure, say N.
191 tristate 'raw table support (required for TRACE)'
192 depends on NETFILTER_ADVANCED
194 This option adds a `raw' table to ip6tables. This table is the very
195 first in the netfilter framework and hooks in at the PREROUTING
198 If you want to compile it as a module, say M here and read
199 <file:Documentation/kbuild/modules.txt>. If unsure, say `N'.
201 # security table for MAC policy
202 config IP6_NF_SECURITY
203 tristate "Security table"
205 depends on NETFILTER_ADVANCED

208 with Mandatory Access Control (MAC) policy.
