Field Description
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.
