If you have control over the NAT device, you could set up a point-to-point
tunnel from the NAT device to the machine in the NAT domain; this would
preserve the public IP address but would require additional routing setup
(assuming that the public subnet is routed by the ISP to the NAT device).

Hope this helps,
