Port Forwarding to more than one device

Maybe this is noob question, but I have not tried it. Can you do port forwarding of the same ports to more than one device connected to the same router? If I have, for example, 3 ATAs, they all use the same ports. How is that handled? Thanks.

Most routers have their own DHCP server that allocates internal IP addresses, so every ATA can have the same port number, since every ATA will have its own unique (internal) IP address, e.g. 192.168.1.x.

However mostly routers use NAT, which means that every IP/port address is remapped by the router so that on the Internet side every ATA has the same IP address but a different port number.

I made a mistake on my question. What I actually wanted to find out about is Port Range Forwarding. Thanks for the response, but I am still not clear as to if it will work. Pls advise.
