Chapter 16 Configuring NAT
Using Dynamic NAT and PAT
Figure 16-18 NAT and PAT Together
See the following commands for this example:
hostname(config)# nat (inside) 1 10.1.2.0 255.255.255.0
hostname(config)#
global (outside) 1 209.165.201.3-209.165.201.4
hostname(config)# global (outside) 1 209.165.201.5
For outside NAT (from outside to inside), you need to use the outside keyword in the nat command. If
you also want to translate the same traffic when it accesses an outside interface (for example, traffic on
a DMZ is translated when accessing the Inside and the Outside interfaces), then you must configure a
separate
nat command without the outside option. In this case, you can identify the same addresses in
both statements and use the same NAT ID. (See Figure 16-19 .) Note that for outside NAT (DMZ interface
to Inside interface), the inside host uses a static command to allow outside access, so both the source
and destination addresses are translated.
