depends on NETFILTER_ADVANCED
select NETFILTER_NETLINK
help
If this option is enabled, the kernel will include support
for extended accounting via NFNETLINK.
config NETFILTER_NETLINK_QUEUE
tristate "Netfilter NFQUEUE over NFNETLINK interface"
depends on NETFILTER_ADVANCED
select NETFILTER_NETLINK
help
If this option is enabled, the kernel will include support
for queueing packets via NFNETLINK.
config NETFILTER_NETLINK_LOG
tristate "Netfilter LOG over NFNETLINK interface"
default m if NETFILTER_ADVANCED=n
select NETFILTER_NETLINK
help
If this option is enabled, the kernel will include support
for logging packets via NFNETLINK.
This obsoletes the existing ipt_ULOG and ebg_ulog mechanisms,
and is also scheduled to replace the old syslog-based ipt_LOG
and ip6t_LOG modules.
config NF_CONNTRACK
tristate "Netfilter connection tracking support"
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 required to do Masquerading or other kinds of Network
Address Translation. It can also be used to enhance packet
filtering (see `Connection state match support' below).
To compile it as a module, choose M here. If unsure, say N.
config NF_LOG_COMMON

config NF_CONNTRACK_MARK
bool 'Connection mark tracking support'
depends on NETFILTER_ADVANCED
help
This option enables support for connection marks, used by the
`CONNMARK' target and `connmark' match. Similar to the mark value
of packets, but this mark value is kept in the conntrack session
instead of the individual packets.
config NF_CONNTRACK_SECMARK
bool 'Connection tracking security mark support'
depends on NETWORK_SECMARK
default m if NETFILTER_ADVANCED=n
help
This option enables security markings to be applied to
connections. Typically they are copied to connections from
packets using the CONNSECMARK target and copied back from
connections to packets with the same target, with the packets
being originally labeled via SECMARK.
If unsure, say 'N'.
config NF_CONNTRACK_ZONES
bool 'Connection tracking zones'
depends on NETFILTER_ADVANCED
depends on NETFILTER_XT_TARGET_CT
help
This option enables support for connection tracking zones.
Normally, each connection needs to have a unique system wide
identity. Connection tracking zones allow to have multiple
connections using the same identity, as long as they are
contained in different zones.
If unsure, say `N'.
