Proxy arp on the NetBSD box should enable communication in the left-to-right
direction.

Try:

	arp -s 204.191.16.3 <ethernet address of 204.191.16.2> pub

A default route on your [Remote] machine to 204.19.16.9 should give you
connectivity right-to-left.

It should also get you access to the rest of the world once proxy arp is
in place and they can answer you.
