Default Server
All Ports

In addition to the servers for specified services, NAT supports a default server. A 

default server receives packets from ports that are not specified in this screen. If

not specified in this screen or remote management will be discarded.

field.

Port Translation 

(start/end)

Enter the port number here to which you want the device to translate the incoming 

port. For a range of ports, you only need to enter the first number of the range to 

which you want the incoming ports translated, the device automatically calculates 

the last port of the translated port range.
