System: NetBSD lapton.mono.org 1.2D NetBSD 1.2D (_LAPTON_) #3: Sun Apr 27 22:24:02 BST 1997 root@lapton.mono.org:/usr/src/sys/arch/i386/compile/_LAPTON_ i386


>Description:
	ipf can be configured from within /etc/rc.conf, but ipnat cannot.
>How-To-Repeat:
	Try to configured a machine to run ipnat on bootup (for example to
	be a gateway for a local subnet all using the same IP address to the
	outside world).
>Fix:
	Patch to /etc/netstart and /etc/rc.conf
