Configuring Network Address Translation (NAT)
Configuring NAT
• Static translation—configured to specific IP addresses and ports; any
configuration changes are made within the NAT configuration itself.
Defining Interfaces as Outside or Inside
NAT configurations have no effect until you map interfaces to NAT by defining
particular interfaces as outside or inside. For example, when traffic arrives on an
inside interface, the module applies the configurations created for inside NAT (as
long as the traffic matches the specifications for that NAT definition).
Note NAT applies to traffic that arrives on an interface. NAT does not affect traffic sent
from an interface.
To define an interface as outside or inside, complete these steps:
1. Select Security > NAT and click the Interfaces tab.
Figure 8-10. Security > NAT > Interfaces Screen
2. Click the Add button. The Add Interface screen is displayed.
