the way that it works, is that the device you are dialing into, dynamically assigns you 1 "real" address. Then you would have your web/http/ftp servers on .201 .203 .204 of you "local" addressing. On the pipeline you would assign static mappings to a port. So it would be like port 80 go to .201 the web server, port 21 got to .202 the ftp server, port 119 go to .203 your newserver... and on and on... so if i wanted to get to your webpage on .201, i would open up my web browser, put in your "real" address, this would go to your pipeline, your pipeline would realize that this is requesting port 80, the pipeline would look to it static mappings and say "this request is for port 80, my mapping say send port 80 to .201" then it will process it to .201. The same for all the other ports... Got it? but no, you can not assign individual address to each device that can be accessed by the "outside world".
