Just DMZ that need to be set to a unique IP.
I've don't believe it's possible to forward the same port to multiple IPs. In fact, most routers won't even let you do that as you can see here:
Also, port forwarding takes priority over DMZ so if you have DMZ set for one IP and port forwarding to another, packets will go to the port forwarded IP.
