Paul,
I am not sure that I understand your problem, so let me tell you what I
understood, before I detail a solution. You have a machine A which is not
connected to any network except an ISP's . It has a static ip-address. You
also have a private network which you want to connect to the internet and you
want the machine A to act as the gateway. Machine A is currently not on the
private network.
I think that you are experiencing difficulty because you believe that one
host can have only one ip-address. This is NOT true. The relationship is more
like one network interface can have only one ip-address. This means that if
you have two ethernet cards in a machine, and they are connected to two
different networks, then the machine can have two ip-addresses. In your case,
your machine A (which should be running ip-masquerading) will have one
statically assigned ip-address for the connection to the ISP, and a private
network address for the ethernet (or any other type of connection you are
using) connection to your private network.
If I have misunderstood your question, or have not addressed your problem,
please let me know.
Kenneth
