Port forwarding to multi IP addresses

Hi,

I just made a firewall dst-nat port X to several ip range (example 192.168.1.81-192.168.1.84), It’s working but I don’t really know how the router decide witch ip address to use. I have been disconnected ports 192.168.1.82-192.168.1.84 and try to connect but it’s not connecting… anything to do?

I would like to make a nat to several ip addresses and the router will decide by who is available (connected)…

Any idea?

A NAT form one and the same port to multiple IP’s is not possible…
