Step 8

If you want the configuration changes to be saved to the startup configuration so
that they are applied the next time the device starts, from the File menu, click

Save

.

Alternatively, ASDM prompts you to save the configuration changes permanently
when you exit ASDM.

If you do not save the configuration changes, the old configuration takes effect
the next time the device starts.

What to Do Next

If you are deploying the security appliance solely to protect a web server in a
DMZ, you have completed the initial configuration.

You may want to consider performing some of the following additional steps:

You can configure the security appliance for more than one application. The
following sections provide configuration procedures for other common
applications of the security appliance.
