area, SDM will perform only one translation.
Check this box if you want to include port information for the outside device in

same public IP address for multiple devices, as long as the port specified for each
device is different.
Click TCP if this is a TCP port number; click UDP if it is a UDP port number.

A dynamic address translation rule dynamically maps hosts to addresses, using
addresses included in a pool of addresses that are globally unique in the
destination network. The pool is defined by specifying a range of addresses and
giving the range a unique name. The configured router uses the available
addresses in the pool (those not used for static translations or for its own WAN IP
address) for connections to the Internet or other outside network. When an address
is no longer in use, it is returned to the address pool to be dynamically assigned
to another device later.
