# # IP netfilter configuration # menu "IPv6: Netfilter Configuration (EXPERIMENTAL)" depends on INET && IPV6 && NETFILTER && EXPERIMENTAL config NF_CONNTRACK_IPV6 tristate "IPv6 support for new connection tracking (EXPERIMENTAL)" depends on EXPERIMENTAL && NF_CONNTRACK ---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)" ---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/masq/NAT)" 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_LIMIT tristate "limit match support" depends on IP6_NF_IPTABLES help limit matching allows you to control the rate at which a rule can be matched: mainly useful in combination with the LOG target ("LOG target support", below) and to avoid some Denial of Service attacks. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_MAC tristate "MAC address match support" depends on IP6_NF_IPTABLES help mac matching allows you to match packets based on the source Ethernet address of the packet. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_RT tristate "Routing header match support" depends on IP6_NF_IPTABLES 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 "Hop-by-hop and Dst opts header match support" depends on IP6_NF_IPTABLES 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 "Fragmentation header match support" depends on IP6_NF_IPTABLES 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 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_MULTIPORT tristate "Multiple port match support" depends on IP6_NF_IPTABLES help Multiport matching allows you to match TCP or UDP packets based on a series of source or destination ports: normally a rule can only match a single range of ports. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_OWNER tristate "Owner match support" depends on IP6_NF_IPTABLES help Packet owner matching allows you to match locally-generated packets based on who created them: the user, group, process or session. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_MARK tristate "netfilter MARK match support" depends on IP6_NF_IPTABLES help Netfilter mark matching allows you to match packets based on the `nfmark' value in the packet. This can be set by the MARK target (see below). To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_IPV6HEADER tristate "IPv6 Extension Headers Match" depends on IP6_NF_IPTABLES 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_AHESP tristate "AH/ESP match support" depends on IP6_NF_IPTABLES help This module allows one to match AH and ESP packets. To compile it as a module, choose M here. If unsure, say N. config IP6_NF_MATCH_LENGTH tristate "Packet Length match support" depends on IP6_NF_IPTABLES help This option allows you to match the length of a packet against a specific value or range of values. 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 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. config IP6_NF_MATCH_PHYSDEV tristate "Physdev match support" depends on IP6_NF_IPTABLES && BRIDGE_NETFILTER help Physdev packet matching matches against the physical bridge ports the IP packet arrived on or will leave by. To compile it as a module, choose M here. If unsure, say N. # The targets config IP6_NF_FILTER tristate "Packet filtering" depends on IP6_NF_IPTABLES 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_LOG tristate "LOG target support" depends on IP6_NF_FILTER 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_TARGET_REJECT tristate "REJECT target support" depends on IP6_NF_FILTER 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_TARGET_NFQUEUE tristate "NFQUEUE Target Support" depends on IP_NF_IPTABLES help This Target replaced the old obsolete QUEUE target. As opposed to QUEUE, it supports 65535 different queues, not just one. 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 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_MARK tristate "MARK target support" depends on IP6_NF_MANGLE help This option adds a `MARK' target, which allows you to create rules in the `mangle' table which alter the netfilter mark (nfmark) field associated with the packet packet prior to routing. This can change the routing method (see `Use netfilter MARK value as routing key') and can also be used by other subsystems to change their behavior. 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 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 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'. endmenu
