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 is enabled, 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_SECMARK
bool 'Connection tracking security mark support'
depends on NF_CONNTRACK && NETWORK_SECMARK
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_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 about changes 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)'

config NETFILTER_XTABLES
tristate "Netfilter Xtables support (required for ip_tables)"
help
This is required if you intend to use any of ip_tables,
ip6_tables or arp_tables.
# alphabetically ordered list of targets
config NETFILTER_XT_TARGET_CLASSIFY
tristate '"CLASSIFY" target support'
depends on NETFILTER_XTABLES
help
This option adds a `CLASSIFY' target, which enables the user to set
the priority of a packet. Some qdiscs can use this value for
classification, among these are:
atm, cbq, dsmark, pfifo_fast, htb, prio
To compile it as a module, choose M here. If unsure, say N.
config NETFILTER_XT_TARGET_CONNMARK
tristate '"CONNMARK" target support'

the connection mark value. Similar to the MARK target, but
affects the connection mark value rather than the packet mark value.

<file:Documentation/modules.txt>. The module will be called
ipt_CONNMARK.o. If unsure, say `N'.
config NETFILTER_XT_TARGET_DSCP

config NETFILTER_XT_TARGET_MARK
tristate '"MARK" target support'
depends on NETFILTER_XTABLES
help

associated with the 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 NETFILTER_XT_TARGET_NFQUEUE

depends on NETFILTER_XTABLES
help

which packets *not* to enter the conntrack/NAT
subsystem with all the consequences (no ICMP error tracking,
no protocol helpers for the selected packets).

depends on NETFILTER_XTABLES && \
((NF_CONNTRACK && NF_CONNTRACK_SECMARK) || \
(IP_NF_CONNTRACK && IP_NF_CONNTRACK_SECMARK))
help
The CONNSECMARK target copies security markings from packets
to connections, and restores security markings from connections
to packets (if the packets are not already marked). This would
normally be used in conjunction with the SECMARK target.
To compile it as a module, choose M here. If unsure, say N.
config NETFILTER_XT_MATCH_COMMENT
tristate '"comment" match support'
