  1. config ADK_KPACKAGE_KMOD_NF_CONNTRACK_IPV4
  2. bool 'IPv4 connection tracking support (required for NAT)'
  3. select ADK_KPACKAGE_KMOD_NF_CONNTRACK
  4. help
  5. Connection tracking keeps a record of what packets have passed
  6. through your machine, in order to figure out how they are related
  7. into connections.
  8. config ADK_KPACKAGE_KMOD_IP_NF_CT_ACCT
  9. bool 'Connection tracking flow accounting'
  10. depends on ADK_KPACKAGE_KMOD_NF_CONNTRACK
  11. help
  12. If this option is enabled, the connection tracking code will
  13. keep per-flow packet and byte counters.
  14. Those counters can be used for flow-based accounting or the
  15. `connbytes' match.
  16. config ADK_KPACKAGE_KMOD_IP_NF_IPTABLES
  17. tristate 'IP tables support (required for filtering/masq/NAT)'
  18. select ADK_KERNEL_NETFILTER_XTABLES
  19. help
  20. iptables is a general, extensible packet identification framework.
  21. The packet filtering and full NAT (masquerading, port forwarding,
  22. etc) subsystems now use this: say `Y' or `M' here if you want to use
  23. either of those.
  24. config ADK_KPACKAGE_KMOD_IP_NF_FILTER
  25. tristate 'Packet Filtering'
  26. depends on ADK_KPACKAGE_KMOD_IP_NF_IPTABLES
  27. help
  28. Packet filtering defines a table `filter', which has a series of
  29. rules for simple packet filtering at local input, forwarding and
  30. local output. See the man page for iptables(8).
  31. config ADK_KPACKAGE_KMOD_NF_NAT
  32. tristate 'Full NAT'
  33. depends on ADK_KPACKAGE_KMOD_NF_IP_IPTABLES
  34. help
  35. The Full NAT option allows masquerading, port forwarding and other
  36. forms of full Network Address Port Translation. It is controlled by
  37. the `nat' table in iptables: see the man page for iptables(8).
  38. config ADK_KPACKAGE_KMOD_IP_NF_TARGET_MASQUERADE
  39. tristate 'MASQUERADE target support'
  40. depends on ADK_KPACKAGE_KMOD_NF_NAT
  41. help
  42. Masquerading is a special case of NAT: all outgoing connections are
  43. changed to seem to come from a particular interface's address, and
  44. if the interface goes down, those connections are lost. This is
  45. only useful for dialup accounts with dynamic IP address (ie. your IP
  46. address will be different on next dialup).
  47. config ADK_KPACKAGE_KMOD_IP_NF_TARGET_REJECT
  48. tristate 'REJECT target support'
  49. depends on ADK_KPACKAGE_KMOD_IP_NF_FILTER
  50. help
  51. The REJECT target allows a filtering rule to specify that an ICMP
  52. error should be issued in response to an incoming packet, rather
  53. than silently being dropped.
  54. config ADK_KPACKAGE_KMOD_IP_NF_TARGET_LOG
  55. tristate 'LOG target support'
  56. depends on ADK_KPACKAGE_KMOD_IP_NF_FILTER
  57. help
  58. This option adds a `LOG' target, which allows you to create rules in
  59. any iptables table which records the packet header to the syslog.
  60. config ADK_KPACKAGE_KMOD_IP_NF_TARGET_ULOG
  61. tristate 'ULOG target support (ipv4 only)'
  62. depends on ADK_KPACKAGE_KMOD_IP_NF_FILTER
  63. help
  64. This option enables the old IPv4-only "ipt_ULOG" implementation
  65. which has been obsoleted by the new "nfnetlink_log" code (see
  66. CONFIG_NETFILTER_NETLINK_LOG).
  67. This option adds a `ULOG' target, which allows you to create rules in
  68. any iptables table. The packet is passed to a userspace logging
  69. daemon using netlink multicast sockets; unlike the LOG target
  70. which can only be viewed through syslog.
  71. The appropriate userspace logging daemon (ulogd) may be obtained from
  72. <http://www.gnumonks.org/projects/ulogd/>
  73. config ADK_KPACKAGE_KMOD_IP_NF_TARGET_REDIRECT
  74. tristate 'REDIRECT target support'
  75. depends on ADK_KPACKAGE_KMOD_NF_NAT
  76. help
  77. REDIRECT is a special case of NAT: all incoming connections are
  78. mapped onto the incoming interface's address, causing the packets to
  79. come to the local machine instead of passing through. This is
  80. useful for transparent proxies.
  81. config ADK_KPACKAGE_KMOD_IP_NF_TARGET_NETMAP
  82. tristate 'NETMAP target support'
  83. depends on ADK_KPACKAGE_KMOD_NF_NAT
  84. help
  85. NETMAP is an implementation of static 1:1 NAT mapping of network
  86. addresses. It maps the network address part, while keeping the host
  87. address part intact. It is similar to Fast NAT, except that
  88. Netfilter's connection tracking doesn't work well with Fast NAT.
  89. config ADK_KPACKAGE_KMOD_IP_NF_MANGLE
  90. tristate 'Packet mangling'
  91. depends on ADK_KPACKAGE_KMOD_NF_NAT
  92. help
  93. This option adds a `mangle' table to iptables: see the man page for
  94. iptables(8). This table is used for various packet alterations
  95. which can effect how the packet is routed.
  96. config ADK_KPACKAGE_KMOD_IP_NF_TARGET_ECN
  97. tristate 'ECN target support'
  98. depends on ADK_KPACKAGE_KMOD_IP_NF_MANGLE
  99. help
  100. This option adds a `ECN' target, which can be used in the iptables mangle
  101. table.
  102. You can use this target to remove the ECN bits from the IPv4 header of
  103. an IP packet. This is particularly useful, if you need to work around
  104. existing ECN blackholes on the internet, but don't want to disable
  105. ECN support in general.
