Say I have a hardware box on an internal network which does a mutant IP
protocol (not TCP or UDP), and I want to send all packets of that
protocol type which arrive at my NetBSD box from the Internet to it, and
likewise send all its outgoing packets of that type out to the net.

I didn't see a syntax in my reading of the ipnat(5) man page for mapping
single IP protocols to/from a host.  Does the kernel machinery have this
capability, and I just need to invent a syntax?
