Suppose I have 2 internal networks: 1.1.1.0/24 and 1.1.2.0/24

I would like to NAT a specific IP address from one network to the other, in which the new address would be obtained via DHCP.

For example: 1.1.1.1 --NAT--> 1.1.2.x (determined via DHCP)

Is this possible via iptables?

EDIT: Forgot to mention NAT is done by a router interfacing both networks.

Is there a specific reason why you need NAT rather than plain routing? –  Hennes Dec 1 '12 at 23:59
    
No specific reason. Only experimentation and learning. –  drum Dec 2 '12 at 0:17
