Is multi nat the anwers to my prayers?
-
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.
