NAPT mode

NAPT is a special case of NAT, where many IP numbers are hidden

behind a number of addresses. In contrast to the original NAT,

however, this does not mean there can be only that number of

connections at a time.

In NAPT mode, an almost arbitrary number of connections are

multiplexed using TCP port information. The number of simultaneous

connections is limited by the number of addresses multiplied by the

number of available TCP ports.
