In lists.freebsd.chat you write:

>are those two things exactly the same and why two different terms?
I've always explained IP masquerading to be a subset of NAT.
NAT is translating
<address range A>:<port range A> to <address range B>:<port range B>
and back, for possibly more than one set of ranges.
Range B need not be range A for both addresses and ports.
If you translate
<address range A>:<port range A> to <single address B>:<port range B>
and only do it once you get IP masquerading, i.e. a whole net hiding
behind a single address.
Maybe the LINUX folks now are able to masquerade to more than one
address, who knows.
