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. menu "Netfilter connection tracking support for special protocols" depends on ADK_KERNEL_NF_CONNTRACK 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: 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 net/ipv4/netfilter/ip_conntrack_pptp.c 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. endmenu config ADK_KERNEL_NETFILTER_NETLINK_LOG tristate 'Netfilter LOG over NFNETLINK interface' help If this option is enabled, the kernel will include support for logging packets via NFNETLINK. menu "Netfilter target support" config ADK_KERNEL_NETFILTER_XT_TARGET_CHECKSUM tristate '"CHECKSUM" target support' select ADK_KERNEL_IP_NF_IPTABLES select ADK_KERNEL_NETFILTER_XTABLES select ADK_KERNEL_IP_NF_MANGLE select ADK_KERNEL_NETFILTER_ADVANCED config ADK_KERNEL_NETFILTER_XT_TARGET_CLASSIFY tristate '"CLASSIFY" target support' select ADK_KERNEL_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 config ADK_KERNEL_NETFILTER_XT_TARGET_CONNMARK tristate '"CONNMARK" target support' select ADK_KERNEL_NETFILTER_XTABLES select ADK_KERNEL_NF_CONNTRACK help 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' depends on ADK_KERNEL_IP_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. config ADK_KERNEL_NETFILTER_XT_TARGET_TCPMSS tristate '"TCPMSS" target support' select ADK_KERNEL_NETFILTER_XTABLES endmenu
