I'm using a standard NetBSD-1.3.2 based ISDN router here with ipf/ipnat
to do the following:
- let one of my machines (actually for that use running NT) hide it's
official IP address from my home network and pretend it's on a
different subnet (at work) over one connection to a customer, but let
it use it's official address via the connection to my isp.
- let an old notebook connected via a plip connection hide it's internal
(plip) network address and map it to it's official address (out of the
range assigned to my ethernet subnet). This saves me some addresses I
would have wasted if I split my official address range further.
I would call both of these "static NAT" - both sides of the translations
are static. And it just works.
