Ah... OK.  Hmm..  I'll look into it, and hopefully come back with a
more intelligent question than simply "What do they do?"

This might be an instance where ssh -L could be your friend.

Assuming 'port forwarding' is the same as 'port redirection' on D-Link
modem-routers (a sort-of reverse NAT), then I've enabled TCP packets
to pass through to 192.168.0.2 on port 22... but it hasn't helped.

I've also tried enabling 'DMZ state' and making 192.168.0.2 the DMZ
IP address... but again, to no avail.

In both cases scp just says 'connection refused'.

No matter because I've found another way.  Emacs users should check out
tramp mode if they haven't heard of it. 

Thanks all.
