What NAT does is map an IP address and port (e.g. 10.0.0.2 tcp port
1050) to an IP address and port on the NetBlazer (the IP address is
probably dynamically allocated by the router that the NetBlazer is
dialing into), in this case lets assume that the NetBlazer is assigned
143.191.100.25, then the above outgoing connection to say www.yahoo.com
port 80 might be allocated port 1234 on the NetBlazer, and yahoo would
think that the incoming connection was from 143.191.100.25 port 1234,
and the NAT could would translate outgoing and incoming packets
accordingly.
