Example: Twice Nat With Destination Address Translation; Nat In Routed And Transparent Mode - Cisco ASA Series Configuration Manual

Chapter 10 NAT Examples and Reference
Add a service object for HTTP:

Configure the second twice NAT rule:
Step 8

destination static TelnetWebServer TelnetWebServer service HTTPObj HTTPObj

Example: Twice NAT with Destination Address Translation

The following figure shows a remote host connecting to a mapped host. The mapped host has a twice
static NAT translation that translates the real address only for traffic to and from the 209.165.201.0/27
network. A translation does not exist for the 209.165.200.224/27 network, so the translated host cannot
connect to that network, nor can a host on that network connect to the translated host.

You can configure NAT in both routed and transparent firewall mode. This section describes typical
usage for each firewall mode.
