3.

The adaptive security appliance translates the destination address to the local
address of the DMZ web server (10.30.30.30) and forwards the packet
through the DMZ interface.

4.

When the DMZ web server responds to the request, the adaptive security
appliance translates the local address of the DMZ web server (10.30.30.30)
to the public address of the DMZ web server (209.165.200.225).

5.

The adaptive security appliance forwards the packet to the outside user.

An Inside User Visits the DMZ Web Server

Figure 8-4

shows an inside user accessing the DMZ web server.
