	The mailing list is correct.

>please. I'm trying to get IPsec working with NetBSD 1.4.2.
>If i have well understood, i have to use files from kame.net .

	I'd really suggest you to switch to plain NetBSD 1.5 (or 1.5.1).
	It should be much easier for you (since IPsec is integrated), and you
	should be able to get more help.

	Reasons:
	- KAME side no longer supports NetBSD 1.4.2
	- KAME tree contains very experimental code, which may not be suitable
	  for your usage
