config ADK_KERNEL_NF_CONNTRACK
	tristate 'Netfilter connection tracking support'
	select ADK_KERNEL_NETFILTER_XTABLES
	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.

config ADK_KERNEL_NF_CONNTRACK_MARK
	bool 'Connection mark tracking support'
	depends on ADK_KERNEL_NF_CONNTRACK
	select ADK_KERNEL_IP_NF_MATCH_CONNMARK
	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 ADK_KERNEL_NF_CONNTRACK_SECMARK
	bool 'Connection tracking security mark support'
	depends on ADK_KERNEL_NF_CONNTRACK
	#FIXME select 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.

config ADK_KERNEL_NF_CONNTRACK_FTP
	tristate 'FTP protocol support'
	depends on ADK_KERNEL_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.

config ADK_KERNEL_NF_CONNTRACK_IRC
	tristate 'IRC protocol support'
	depends on ADK_KERNEL_NF_CONNTRACK
	help
	  There is a commonly-used extension to IRC called
	  Direct Client-to-Client Protocol (DCC).  This enables users to send
	  files to each other, and also chat to each other without the need
	  of a server.  DCC Sending is used anywhere you send files over IRC,
	  and DCC Chat is most commonly used by Eggdrop bots.  If you are
	  using NAT, this extension will enable you to send files and initiate
	  chats.  Note that you do NOT need this extension to get files or
	  have others initiate chats, or everything else in IRC.

config ADK_KERNEL_NF_CONNTRACK_NETBIOS_NS
	tristate 'NetBIOS name service protocol support'
	depends on ADK_KERNEL_NF_CONNTRACK
	help
	  NetBIOS name service requests are sent as broadcast messages from an
	  unprivileged port and responded to with unicast messages to the
	  same port. This make them hard to firewall properly because connection
	  tracking doesn't deal with broadcasts. This helper tracks locally
	  originating NetBIOS name service requests and the corresponding
	  responses. It relies on correct IP address configuration, specifically
	  netmask and broadcast address. When properly configured, the output
	  of "ip address show" should look similar to this:

	  $ ip -4 address show eth0
	  4: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
	      inet 172.16.2.252/24 brd 172.16.2.255 scope global eth0

config ADK_KERNEL_NF_CONNTRACK_TFTP
	tristate 'TFTP protocol support'
	depends on ADK_KERNEL_NF_CONNTRACK
	help
	  TFTP connection tracking helper, this is required depending
	  on how restrictive your ruleset is.
	  If you are using a tftp client behind -j SNAT or -j MASQUERADING
	  you will need this.

config ADK_KERNEL_NF_CONNTRACK_PPTP
	tristate 'PPTP protocol support'
	depends on ADK_KERNEL_NF_CONNTRACK
	help
	  This module adds support for PPTP (Point to Point Tunnelling
	  Protocol, RFC2637) connection tracking and NAT. 
	
	  If you are running PPTP sessions over a stateful firewall or NAT
	  box, you may want to enable this feature.  
	
	  Please note that not all PPTP modes of operation are supported yet.
	  For more info, read top of the file

config ADK_KERNEL_NF_CONNTRACK_H323
	tristate 'H.323 protocol support'
	depends on ADK_KERNEL_NF_CONNTRACK
	help
	  H.323 is a VoIP signalling protocol from ITU-T. As one of the most
	  important VoIP protocols, it is widely used by voice hardware and
	  software including voice gateways, IP phones, Netmeeting, OpenPhone,
	  Gnomemeeting, etc.

	  With this module you can support H.323 on a connection tracking/NAT
	  firewall.

	  This module supports RAS, Fast Start, H.245 Tunnelling, Call
	  Forwarding, RTP/RTCP and T.120 based audio, video, fax, chat,
	  whiteboard, file transfer, etc. For more information, please
	  visit http://nath323.sourceforge.net/.

config ADK_KERNEL_NF_CONNTRACK_SIP
	tristate 'SIP protocol support'
	depends on ADK_KERNEL_NF_CONNTRACK
	help
	  SIP is an application-layer control protocol that can establish,
	  modify, and terminate multimedia sessions (conferences) such as
	  Internet telephony calls. With the ip_conntrack_sip and
	  the ip_nat_sip modules you can support the protocol on a connection
	  tracking/NATing firewall.

	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

config ADK_KERNEL_NETFILTER_XT_TARGET_CONNMARK
	tristate '"CONNMARK" target support'
	select ADK_KERNEL_NETFILTER_XTABLES

	  This option adds a `CONNMARK' target, which allows one to manipulate
	  the connection mark value.  Similar to the MARK target, but
	  affects the connection mark value rather than the packet mark value.

config ADK_KERNEL_NETFILTER_XT_TARGET_MARK
	tristate '"MARK" target support'
	select ADK_KERNEL_NETFILTER_XTABLES
	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 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.

config ADK_KERNEL_NETFILTER_XT_TARGET_NFQUEUE
	tristate '"NFQUEUE" target support'
	select ADK_KERNEL_NETFILTER_XTABLES
	help
	  This target replaced the old obsolete QUEUE target.

	  As opposed to QUEUE, it supports 65535 different queues,
	  not just one.

config ADK_KERNEL_NETFILTER_XT_TARGET_LOG
	tristate '"LOG" target support'
