Looks to me like you don't have the necessary devices.  First, make sure
that you have all 3 of the following in your /dev directory:

	crw-------  1 root  wheel   35,   0 Nov  7 16:36 /dev/ipl
	crw-------  1 root  wheel   35,   1 Nov  7 16:36 /dev/ipnat
	crw-------  1 root  wheel   35,   2 Nov  7 16:36 /dev/ipstate

You also need to have a kernel with all of the ipnat stuff compiled in,
but most GENERIC kernels include this, I think.
