As long as you have only one public IP address, you'll have to put a device (sofware or hardware)
between your servers (private IP addresses), and the internet.
That can be NAT, but the port issue is not very nice for clients. Or, that can be a proxy,
who will act almost like a NAT, but on the application level.
Your proxy can be an Apache Server, with mod_proxy, setup to forward client requests for
to server1, and to server2. That's not an unusual setup. 
That could also be a Layer 7 switch, but it's very expensive, doing exactly the same job (somewhat
easier to configure).
