Chapter 5 Configuring Twice NAT (ASA 8.3 and Later)

Configuration Examples for Twice NAT

c.Choose the new network object by double-clicking it. Click OK to return to the NAT configuration.

Step 15 For the Translated Destination Address, type the name of the Original Destination Address (DMZnetwork2) or click the browse button to choose it.

Because you do not want to translate the destination address, you need to configure identity NAT for it by specifying the same address for the Original and Translated destination addresses.

Step 16 Click OK to add the rule to the NAT table.

Step 17 Click Apply.
