NAT is natural Address Translation where you change the originating IP
address to another external IP address on leaving the firewall. On the
return, the IP address is translated back to the originating IP address.
This is used most often when you do not have enough "legal" internet IP
addresses, and want to allow multiple users to access the internet.
An example would be to have an internal IP of say 10.10.1.1 which is NAT'd
to 192.178.23.47 (valid IP address) when leaving, and translated on the
return back to 10.10.1.1. So the internet will see your IP as 192.178.23.47
and not as 10.10.1.1.
IP Masquerading is (if I'm not mistaken) the same or similar to IP spoofing.
