No problem, I do the same thing at home, with both  routable and
non-routable networks on my LAN, both forwarded out my ppp link.

1. Configure your NetBSD box with 2 addresses on the LAN interface.
   Put the "routable" address in your ifconfig.<interface> file.  And
   put the non-routable address in your ifaliases file:
	172.16.1.1	ex0	255.255.0.0

2. Then just configure NAT to translate from the non-routable network
   to the real one.

	map ppp0 172.16.249.206/32 -> 209.182.147.67/32
