menu "Core Netfilter Configuration"
depends on NET && NETFILTER
config NETFILTER_NETLINK
tristate "Netfilter netlink interface"
help
If this option is enabled, the kernel will include support
for the new netfilter netlink interface.
config NETFILTER_NETLINK_QUEUE
tristate "Netfilter NFQUEUE over NFNETLINK interface"
depends on NETFILTER_NETLINK
help
If this option isenabled, the kernel will include support
for queueing packets via NFNETLINK.
config NETFILTER_NETLINK_LOG
tristate "Netfilter LOG over NFNETLINK interface"
depends on 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 "Layer 3 Independent Connection tracking (EXPERIMENTAL)"
depends on EXPERIMENTAL && IP_NF_CONNTRACK=n
default 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.
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 NF_CT_ACCT
bool "Connection tracking flow accounting"
depends on NF_CONNTRACK
help
If this option is enabled, the connection tracking code will
keep per-flow packet and byte counters.
Those counters can be used for flow-based accounting or the
`connbytes' match.
If unsure, say `N'.
config NF_CONNTRACK_MARK
bool 'Connection mark tracking support'
depends on NF_CONNTRACK
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_EVENTS
bool "Connection tracking events (EXPERIMENTAL)"
depends on EXPERIMENTAL && NF_CONNTRACK
help
If this option is enabled, the connection tracking code will
provide a notifier chain that can be used by other kernel code
to get notified aboutchanges in the connection tracking state.
If unsure, say `N'.
config NF_CT_PROTO_SCTP
tristate 'SCTP protocol on new connection tracking support (EXPERIMENTAL)'
depends on EXPERIMENTAL && NF_CONNTRACK
default n
help
With this option enabled, the layer 3 independent connection
tracking code will be able to do state tracking on SCTP connections.
If you want to compile it as a module, say M here and read
Documentation/modules.txt. If unsure, say `N'.
config NF_CONNTRACK_FTP
tristate "FTP support on new connection tracking (EXPERIMENTAL)"
depends on EXPERIMENTAL && NF_CONNTRACK
help
Tracking FTP connections is problematic: special helpers are
required for tracking them, and doing masquerading and other forms
of Network Address Translation on them.
This is FTP 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 NF_CT_NETLINK
tristate 'Connection tracking netlink interface (EXPERIMENTAL)'
depends on EXPERIMENTAL && NF_CONNTRACK && NETFILTER_NETLINK
depends on NF_CONNTRACK!=y || NETFILTER_NETLINK!=m
help
This option enables support for a netlink-based userspace interface
