6(Optional) Allowing Access to Public Servers Behind the
ASA
The Public Server pane automatically configures the security policy to make an inside server accessible from the Internet. As a business owner, you might have internal network services, such as a web and FTP server, that need to be available to an outside user. You can place these services on a separate network behind the ASA, called a demilitarized zone (DMZ). By placing the public servers on the DMZ, any attacks launched against the public servers do not affect your inside networks.
Step 1 In the main ASDM window, choose Configuration > Firewall > Public Servers. The Public Server pane appears.
Step 2 Click Add, then enter the public server settings in the Add Public Server dialog box. (For information about any field, click Help.)
Step 3 Click OK. The server appears in the list.
Step 4 Click Apply to submit the configuration to the ASA.
