7 (Optional) Allowing Access to Public Servers Behind the
ASA
ASA 8.2 and Later
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.
