      Forgive my ignorance but I have been trying to figure this out all day :).

      I have a cable modem which can hand out 2 public DYNAMIC IP's. So if I were to connect a switch to this modem, 2 devices connected to this switch will be able to receive a public IP. Anyway, I have about 6 devices so I needed to deploy NAT. My LAN subnet is 192.168.0.x.

      Normally, a router will receive a (one) public IP on its WAN port. I need a way to assign the 2nd public IP I am allowed to use to a device in my 192.168.0.x LAN. So all LAN devices but 1 will have a 192.168.0.x IP and 1 device will have a public IP (obviously the router's WAN port will have the second public IP).

      Is this possible or am I imagining things? It seems multi nat requires FIXED public IP's and cannot work with dynamic public IP's? I hope some smarter guy than me can shed some light onto this:-)

      Thanks!

        Why do you need to use both public ips?  I would assign 1 of the 2 to the wan port and leave the second one alone.  I wouldn't "assign" it at all actually.  I would set the wan interface to use dynamic ip.  Then nat behind that.
