this seems to work like my ISP. I have at the end a private IP address in the range 10.x.y.z. They do the translation when needed for me. Of course, my machine is not accessible from outside.

What confuses me is that your XP machine gets a 192.168 address between. How can it access the DHCP then? Can you try to limit the address range to 10.x.y.z during the negotiation phase?

How do you connect to the cable? Is there some kind of a 'modem'?
