# # IP netfilter configuration # menu "IPv6: Netfilter Configuration" depends on INET && IPV6 && NETFILTER config NF_CONNTRACK_IPV6 tristate "IPv6 connection tracking support" depends on INET && IPV6 && NF_CONNTRACK default m if NETFILTER_ADVANCED=n ---help--- Connection tracking keeps a record of what packets have passed through your machine, in order to figure out how they are related into connections. This is IPv6 support on Layer 3 independent connection tracking. Layer 3 independent connection tracking is experimental scheme which generalize ip_conntrack to support other layer 3 protocols. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_QUEUE tristate "IP6 Userspace queueing via NETLINK (OBSOLETE)" depends on INET && IPV6 && NETFILTER depends on NETFILTER_ADVANCED ---help--- This option adds a queue handler to the kernel for IPv6 packets which enables users to receive the filtered packets with QUEUE target using libipq. This option enables the old IPv6-only "ip6_queue" implementation which has been obsoleted by the new "nfnetlink_queue" code (see CONFIG_NETFILTER_NETLINK_QUEUE).

To compile it as a module, choose M here. If unsure, say N. config IP6_NF_IPTABLES tristate "IP6 tables support (required for filtering)" depends on INET && IPV6 select NETFILTER_XTABLES default m if NETFILTER_ADVANCED=n help ip6tables is a general, extensible packet identification framework. Currently only the packet filtering and packet mangling subsystem for IPv6 use this, but connection tracking is going to follow. Say 'Y' or 'M' here if you want to use either of those. To compile it as a module, choose M here. If unsure, say N. # The simple matches. config IP6_NF_MATCH_RT tristate '"rt" Routing header match support' depends on IP6_NF_IPTABLES depends on NETFILTER_ADVANCED help rt matching allows you to match packets based on the routing header of the packet. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_OPTS tristate '"hbh" hop-by-hop and "dst" opts header match support' depends on IP6_NF_IPTABLES depends on NETFILTER_ADVANCED help This allows one to match packets based on the hop-by-hop and destination options headers of a packet. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_FRAG tristate '"frag" Fragmentation header match support' depends on IP6_NF_IPTABLES depends on NETFILTER_ADVANCED help frag matching allows you to match packets based on the fragmentation header of the packet. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_HL tristate '"hl" match support' depends on IP6_NF_IPTABLES depends on NETFILTER_ADVANCED help HL matching allows you to match packets based on the hop limit of the packet. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_IPV6HEADER tristate '"ipv6header" IPv6 Extension Headers Match' depends on IP6_NF_IPTABLES default m if NETFILTER_ADVANCED=n help This module allows one to match packets based upon the ipv6 extension headers. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_AH tristate '"ah" match support' depends on IP6_NF_IPTABLES depends on NETFILTER_ADVANCED help This module allows one to match AH packets. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_MH tristate '"mh" match support' depends on IP6_NF_IPTABLES depends on NETFILTER_ADVANCED help This module allows one to match MH packets. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_EUI64 tristate '"eui64" address check' depends on IP6_NF_IPTABLES depends on NETFILTER_ADVANCED help This module performs checking on the IPv6 source address Compares the last 64 bits with the EUI64 (delivered from the MAC address) address To compile it as a module, choose M here. If unsure, say N. # The targets config IP6_NF_TARGET_LOG tristate "LOG target support" depends on IP6_NF_IPTABLES default m if NETFILTER_ADVANCED=n help This option adds a `LOG' target, which allows you to create rules in any iptables table which records the packet header to the syslog. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_FILTER tristate "Packet filtering" depends on IP6_NF_IPTABLES default m if NETFILTER_ADVANCED=n help Packet filtering defines a table `filter', which has a series of rules for simple packet filtering at local input, forwarding and local output. See the man page for iptables(8). To compile it as a module, choose M here. If unsure, say N. config IP6_NF_TARGET_REJECT tristate "REJECT target support" depends on IP6_NF_FILTER default m if NETFILTER_ADVANCED=n help The REJECT target allows a filtering rule to specify that an ICMPv6 error should be issued in response to an incoming packet, rather than silently being dropped. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MANGLE tristate "Packet mangling" depends on IP6_NF_IPTABLES default m if NETFILTER_ADVANCED=n help This option adds a `mangle' table to iptables: see the man page for iptables(8). This table is used for various packet alterations which can effect how the packet is routed. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_TARGET_HL tristate 'HL (hoplimit) target support' depends on IP6_NF_MANGLE depends on NETFILTER_ADVANCED help This option adds a `HL' target, which enables the user to decrement the hoplimit value of the IPv6 header or set it to a given (lower) value. While it is safe to decrement the hoplimit value, this option also enables functionality to increment and set the hoplimit value of the IPv6 header to arbitrary values. This is EXTREMELY DANGEROUS since you can easily create immortal packets that loop forever on the network. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_RAW tristate 'raw table support (required for TRACE)' depends on IP6_NF_IPTABLES depends on NETFILTER_ADVANCED help This option adds a `raw' table to ip6tables. This table is the very first in the netfilter framework and hooks in at the PREROUTING and OUTPUT chains. If you want to compile it as a module, say M here and read . If unsure, say `N'. # security table for MAC policy config IP6_NF_SECURITY tristate "Security table" depends on IP6_NF_IPTABLES depends on SECURITY depends on NETFILTER_ADVANCED help This option adds a `security' table to iptables, for use with Mandatory Access Control (MAC) policy. If unsure, say N. endmenu
