5 menu "IPv6: Netfilter Configuration (EXPERIMENTAL)"
6 depends on INET && IPV6 && NETFILTER && EXPERIMENTAL
8 config NF_CONNTRACK_IPV6
9 tristate "IPv6 support for new connection tracking (EXPERIMENTAL)"
10 depends on EXPERIMENTAL && NF_CONNTRACK
12 Connection tracking keeps a record of what packets have passed
13 through your machine, in order to figure out how they are related
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.
20 To compile it as a module, choose M here. If unsure, say N.
23 tristate "IP6 Userspace queueing via NETLINK (OBSOLETE)"
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.
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).

42 config IP6_NF_IPTABLES
43 tristate "IP6 tables support (required for filtering/masq/NAT)"
44 depends on NETFILTER_XTABLES
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.
51 To compile it as a module, choose M here. If unsure, say N.
54 config IP6_NF_MATCH_RT
55 tristate "Routing header match support"
56 depends on IP6_NF_IPTABLES
58 rt matching allows you to match packets based on the routing
61 To compile it as a module, choose M here. If unsure, say N.
63 config IP6_NF_MATCH_OPTS
64 tristate "Hop-by-hop and Dst opts header match support"
65 depends on IP6_NF_IPTABLES
67 This allows one to match packets based on the hop-by-hop
68 and destination options headers of a packet.
70 To compile it as a module, choose M here. If unsure, say N.
72 config IP6_NF_MATCH_FRAG
73 tristate "Fragmentation header match support"
74 depends on IP6_NF_IPTABLES
76 frag matching allows you to match packets based on the fragmentation
79 To compile it as a module, choose M here. If unsure, say N.
81 config IP6_NF_MATCH_HL
82 tristate "HL match support"
83 depends on IP6_NF_IPTABLES
85 HL matching allows you to match packets based on the hop
88 To compile it as a module, choose M here. If unsure, say N.
90 config IP6_NF_MATCH_MULTIPORT
91 tristate "Multiple port match support"
92 depends on IP6_NF_IPTABLES
94 Multiport matching allows you to match TCP or UDP packets based on
95 a series of source or destination ports: normally a rule can only
96 match a single range of ports.
98 To compile it as a module, choose M here. If unsure, say N.
100 config IP6_NF_MATCH_OWNER
101 tristate "Owner match support"
102 depends on IP6_NF_IPTABLES
104 Packet owner matching allows you to match locally-generated packets
105 based on who created them: the user, group, process or session.
107 To compile it as a module, choose M here. If unsure, say N.
109 config IP6_NF_MATCH_IPV6HEADER
110 tristate "IPv6 Extension Headers Match"
111 depends on IP6_NF_IPTABLES
113 This module allows one to match packets based upon
114 the ipv6 extension headers.
116 To compile it as a module, choose M here. If unsure, say N.
118 config IP6_NF_MATCH_AHESP
119 tristate "AH/ESP match support"
120 depends on IP6_NF_IPTABLES
122 This module allows one to match AH and ESP packets.
124 To compile it as a module, choose M here. If unsure, say N.
126 config IP6_NF_MATCH_EUI64
127 tristate "EUI64 address check"
128 depends on IP6_NF_IPTABLES
130 This module performs checking on the IPv6 source address
131 Compares the last 64 bits with the EUI64 (delivered
132 from the MAC address) address
134 To compile it as a module, choose M here. If unsure, say N.
138 tristate "Packet filtering"
139 depends on IP6_NF_IPTABLES
141 Packet filtering defines a table `filter', which has a series of
142 rules for simple packet filtering at local input, forwarding and
143 local output. See the man page for iptables(8).
145 To compile it as a module, choose M here. If unsure, say N.
147 config IP6_NF_TARGET_LOG
148 tristate "LOG target support"
149 depends on IP6_NF_FILTER
151 This option adds a `LOG' target, which allows you to create rules in
152 any iptables table which records the packet header to the syslog.
154 To compile it as a module, choose M here. If unsure, say N.
156 config IP6_NF_TARGET_REJECT
157 tristate "REJECT target support"
158 depends on IP6_NF_FILTER
160 The REJECT target allows a filtering rule to specify that an ICMPv6
161 error should be issued in response to an incoming packet, rather
162 than silently being dropped.
164 To compile it as a module, choose M here. If unsure, say N.
167 tristate "Packet mangling"
168 depends on IP6_NF_IPTABLES
170 This option adds a `mangle' table to iptables: see the man page for
171 iptables(8). This table is used for various packet alterations
172 which can effect how the packet is routed.
174 To compile it as a module, choose M here. If unsure, say N.
176 config IP6_NF_TARGET_HL
177 tristate 'HL (hoplimit) target support'
178 depends on IP6_NF_MANGLE
180 This option adds a `HL' target, which enables the user to decrement
181 the hoplimit value of the IPv6 header or set it to a given (lower)
184 While it is safe to decrement the hoplimit value, this option also
185 enables functionality to increment and set the hoplimit value of the
186 IPv6 header to arbitrary values. This is EXTREMELY DANGEROUS since
187 you can easily create immortal packets that loop forever on the
190 To compile it as a module, choose M here. If unsure, say N.
193 tristate 'raw table support (required for TRACE)'
194 depends on IP6_NF_IPTABLES
196 This option adds a `raw' table to ip6tables. This table is the very
197 first in the netfilter framework and hooks in at the PREROUTING
200 If you want to compile it as a module, say M here and read
201 <file:Documentation/modules.txt>. If unsure, say `N'.
