CONFIG_IP_NF_TARGET_TTL: 'TTL' target support

General informations

The Linux kernel configuration item CONFIG_IP_NF_TARGET_TTL has multiple definitions:

'TTL' target support found in net/ipv4/netfilter/Kconfig

The configuration item CONFIG_IP_NF_TARGET_TTL:

• prompt: 'TTL' target support
• type: tristate
• depends on: CONFIG_NETFILTER_ADVANCED && CONFIG_IP_NF_MANGLE
• defined in net/ipv4/netfilter/Kconfig
• found in Linux kernels: 2.6.30–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: ipt_TTL

Help text

This is a backwards-compatible option for the user's convenience (e.g. when running oldconfig). It selects NETFILTER_XT_TARGET_HL.

TTL target support found in net/ipv4/netfilter/Kconfig

The configuration item CONFIG_IP_NF_TARGET_TTL:

• prompt: TTL target support
• type: tristate
• depends on: ( CONFIG_IP_NF_MANGLE ) && ( CONFIG_NETFILTER_ADVANCED )
• defined in net/ipv4/netfilter/Kconfig
• found in Linux kernels: 2.6.14–2.6.29
• modules built: ipt_TTL

Help text

This option adds a `TTL' target, which enables the user to modify the TTL value of the IP header.

While it is safe to decrement/lower the TTL, this target also enables functionality to increment and set the TTL value of the IP header to arbitrary values. This is EXTREMELY DANGEROUS since you can easily create immortal packets that loop forever on the network.

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