There doesn't seem to be anything wrong with your setup, assuming that
the subnet value is correct. Does this help?

	route add 128.255.53.143 localhost -iface

But you're not supposed to need that.

That means the gateway is unreachable, which you already knew. Is the
other mac set up the same way, static ip and fixed subnet of /22? If
it's using DHCP, for instance, then you need to do something on the
gateway to make your netbsd system work.
