Configuring Network Address Translation
117356-B Rev. 00
12-5
NAT software detects a packet on a NAT interface that contains the address
10.0.0.15 (Figure 12-2).
Figure 12-2. NAT Detects the Unregistered Source Address
NAT software dynamically maps the unregistered source address, 10.0.0.15, to
one of the available registered global addresses (in this case, 192.55.10.3) and
puts a new entry in the local/global mapping entry list (Figure 12-3).
