STEP ONE

The first step in the configuration of NAT is to enable NAT and choose the NAT Mode (Normal or Extended). Only the extended mode is discussed in this chapter. The normal mode is a previous version of NAT maintained for backwards compatability. See chapter 4 of the CyROS Reference Guide for information about the Normal Mode.
