Avocent Cyclades-PR2000 NAT Enabled NAT mode Expanded Port map translation Enabled, 192.168.0.0

Cyclades-PR2000

There are two types of NAT available in CyROS -- Normal NAT and Expanded NAT. This chapter describes Expanded NAT. A description of Normal NAT appears in Chapter 4 of the CyROS Reference Guide.

What is the difference between Expanded and Normal Mode NAT? The Normal Mode is a previous implementation of NAT used in the Power Router line. It has been maintained for backward compatibility. Expanded NAT provides static translation not only from one IP address to another, but from one IP address/port pair to another IP address/port pair.

As a preview, after configuring the router as shown in the example, CONFIG =>SECURITY =>NAT =>L will display:
