What's the different between NAT and TCP/UDP mapping? I thought they both get your network up by using only one ip address. No?

NAT is generic, it grabs random TCP/UDP ports. (not really, but it's close enough for a quick explanation).

TCP mapping is directing a *specific* port to another, usually for security. So any request to port 80 actually goes to port 7865, or whatever. This way I can see you from seeing what REAL ports I'm using for applications.
