CONFIG_NF_CONNTRACK: Netfilter connection tracking support

General informations

The Linux kernel configuration item CONFIG_NF_CONNTRACK has multiple definitions:

Netfilter connection tracking support found in net/netfilter/Kconfig

The configuration item CONFIG_NF_CONNTRACK:

• prompt: Netfilter connection tracking support
• type: tristate
• depends on: CONFIG_NETFILTER_ADVANCED = CONFIG_n
• defined in net/netfilter/Kconfig
• found in Linux kernels: 2.6.25–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.17, 6.18-rc+HEAD
• modules built: nf_conntrack

Help text

Connection tracking keeps a record of what packets have passed through your machine, in order to figure out how they are related into connections.

This is required to do Masquerading or other kinds of Network Address Translation. It can also be used to enhance packet filtering (see `Connection state match support' below).

To compile it as a module, choose M here. If unsure, say N.

Layer 3 Independent Connection tracking (EXPERIMENTAL) found in net/netfilter/Kconfig

The configuration item CONFIG_NF_CONNTRACK:

• prompt: Layer 3 Independent Connection tracking (EXPERIMENTAL)
• type: tristate
• depends on: CONFIG_EXPERIMENTAL && CONFIG_IP_NF_CONNTRACK = CONFIG_n
• defined in net/netfilter/Kconfig
• found in Linux kernels: 2.6.15–2.6.19
• modules built: nf_conntrack

Help text

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.
