Configuring Network Address Translation (NAT)
Overview
However, for destination NAT, the local address is actually the address as it appears
across the border between inside and outside. This is because packets, pre-translation,
are destined to the IP address that the originating station knows for the destination
device, not the destination’s actual IP address. In Figure 8-5 on page 8-10, for
example, the local address is 10.1.1.1.
Table 8-2 summarizes this terminology.
