+ ---help---
+ This option adds the "HL" (for IPv6) and "TTL" (for IPv4)
+ targets, which enable the user to change the
+ hoplimit/time-to-live value of the IP header.
+
+ While it is safe to decrement the hoplimit/TTL value, the
+ modules also allow to increment and set the hoplimit value of
+ the header to arbitrary values. This is EXTREMELY DANGEROUS
+ since you can easily create immortal packets that loop
+ forever on the network.

+config NETFILTER_XT_TARGET_LED

+ depends on LEDS_CLASS && LED_TRIGGERS
+ depends on NETFILTER_ADVANCED
+ help
+ This option adds a `LED' target, which allows you to blink LEDs in
+ response to particular packets passing through your machine.
+
+ This can be used to turn a spare LED into a network activity LED,
+ which only flashes in response to FTP transfers, for example. Or
+ you could have an LED which lights up for a minute or two every time
+ somebody connects to your machine via SSH.
+
+ You will need support for the "led" class to make this work.
+
+ To create an LED trigger for incoming SSH traffic:
+ iptables -A INPUT -p tcp --dport 22 -j LED --led-trigger-id ssh --led-delay 1000
+
+ Then attach the new trigger to an LED on your system:
+ echo netfilter-ssh > /sys/class/leds/<ledname>/trigger
+
+ For more information on the LEDs available on your system, see
+ Documentation/leds-class.txt

+ ---help---
+ This option allows you to build work-load-sharing clusters of
+ network servers/stateful firewalls without having a dedicated
+ load-balancing router/server/switch. Basically, this match returns
+ true when the packet must be handled by this cluster node. Thus,
+ all nodes see all packets and this match decides which node handles
+ what packets. The work-load sharing algorithm is based on source
+ address hashing.

+ If you say Y or M here, try `iptables -m cluster --help` for
+ more information.
