	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/leds-class.txt

	  This option adds a `TCPMSS' target, which allows you to alter the
	  MSS value of TCP SYN packets, to control the maximum size for that
	  connection (usually limiting it to your outgoing interface's MTU
	  minus 40).

	  This is used to overcome criminally braindead ISPs or servers which
	  block ICMP Fragmentation Needed packets.  The symptoms of this
	  problem are that everything works fine from your Linux
	  firewall/router, but machines behind it can never exchange large
	  packets:
	        1) Web browsers connect, then hang with no data received.
	        2) Small mail works fine, but large emails hang.
	        3) ssh works fine, but scp hangs after initial handshaking.

	  Workaround: activate this option and add a rule to your firewall
	  configuration like:

	  iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
	                 -j TCPMSS --clamp-mss-to-pmtu
