Thomas,

NAT (Network Address Translation) - every inside (private) address is directly
translated to a valid (public) outside address - one to one.

eg 10.1.1.1 ----> 144.1.1.1
   10.1.1.2 ----> 144.1.1.2

PAT (Port Address Translation) - every inside address is translated using one
or more addresses but using also the ports number also to specify the
connection. Each ip address can have 4000 translations on it.

eg 10.1.1.1 ----> 144.1.1.1:1025
   10.1.1.2 ----> 144.1.1.1:1026
        .               .
        .               .
        .               .
   10.1.255.1 -----> 144.1.2:2002
