You cannot, this breaks fundamental rules of IP networking. All nodes
must have unique IP address.

If you want to forward from the WAN interface (i.e. outside your
network) to a machine in your LAN, use Inbound NAT rules. Make sure to
tick the auto-create firewall rule box. 

If you want to redirect traffic from one machine to another on your LAN,
I'm not sure you can do that. There has been some chatter about
redirecting SMTP, I would start with searching the archive on that.
