<div>The example you're using IS ALREADY mapping multiple ports. It is mapping host port 2323 to simulated system port 23 AND host port 2121 to simulated system port 21. This maps telnet (on port 23) and ftp (on port 21).<br></div>
<div><br></div>
<div>You can add additional mappings on the same command line up to some reasonably large command line length limit.<br></div>
