3 ConfiguringtheCiscoASA5500SeriesAdaptiveSecurity

Appliance

This section describes the initial configuration of the adaptive security appliance. You can perform the

configuration steps using either the browser-based Cisco Adaptive Security Device Manager (ASDM)

or the command-line interface (CLI).

Note To use ASDM, you must have a DES license or a 3DES-AES license. For more information,

see Obtaining DES and 3DES/AES Encryption Licenses, page 52.

About the Factory Default Configuration

Cisco adaptive security appliances are shipped with a factory-default configuration that enables quick

startup. This configuration meets the needs of most small and medium business networking

environments. By default, the adaptive security appliance is configured as follows:

•The inside (GigabitEthernet0/1) interface is configured with a default DHCP address pool.

This configuration enables a client on the inside network to obtain a DHCP address from the

adaptive security appliance in order to connect to the appliance. Administrators can then

configure and manage the adaptive security appliance using ASDM.

•The outside (GigabitEthernet0/0) interface is used to connect to the public network and is

configured to deny all inbound traffic.

This configuration protects your inside network from unsolicited traffic.

Based on your network security policy, you should also consider configuring the adaptive security

appliance to deny all ICMP traffic through the outside interface or any other interface that is necessary.

You can configure this access control policy using the icmp command. For more information about the

icmp command, see the Cisco Security Appliance Command Reference.

About the Adaptive Security Device Manager

The Adaptive Security Device

Manager (ASDM) is a feature-rich

graphical interface that enables you to

manage and monitor the adaptive

security appliance. Its web-based

design provides secure access so that

you can connect to and manage the

adaptive security appliance from any

location by using a web browser.

In addition to complete configuration

and management capability, ASDM

features intelligent wizards to simplify

and accelerate the deployment of the

adaptive security appliance.

To use ASDM, you must have a DES

license or a 3DES-AES license. In

addition, Java and JavaScript must be

enabled in your web browser.

About Configuration from the Command-Line Interface

In addition to the ASDM web configuration tool, you can configure the adaptive security appliance by

using the command-line interface. For more information, see the Cisco Security Appliance Command

Line Configuration Guide and the Cisco Security Appliance Command Reference.

Using the Startup Wizard

ASDM includes a Startup Wizard to simplify the initial configuration of your adaptive security

appliance. With a few steps, the Startup Wizard enables you to configure the adaptive security appliance

so that it allows packets to flow securely between the inside network (GigabitEthernet0/1) and the outside

network (GigabitEthernet0/0).

Before you launch the Startup Wizard, gather the following information:

•A unique hostname to identify the adaptive security appliance on your network.

•The IP addresses of your outside interface, inside interface, and any other interfaces.

•The IP addresses to use for NAT or PAT configuration.

•The IP address range for the DHCP server.

To use the Startup Wizard to set up a basic configuration for the adaptive security appliance, perform

the following steps:

Step 1 If you have not already done so, complete one of the following steps:

•If you have an ASA 5520 or 5540, connect the inside GigabitEthernet0/1 interface to a

switch or hub by using the Ethernet cable. To this same switch, connect a PC for

configuring the adaptive security appliance.

•If you have an ASA 5510, connect the inside Ethernet 1 interface to a switch or hub by

using the Ethernet cable. To this same switch, connect a PC for configuring the adaptive

security appliance.

Step 2 Configure your PC to use DHCP (to receive an IP address automatically from the adaptive

security appliance), or assign a static IP address to your PC by selecting an address out of the

192.168.1.0 network. (Valid addresses are 192.168.1.2 through 192.168.1.254, with a mask of

255.255.255.0 and default route of 192.168.1.1.)

Note The inside interface of the adaptive security appliance is assigned 192.168.1.1 by

default, so this address is unavailable.

Step 3 Complete one of the following steps:

•If you have an ASA 5520 or 5540, check the LINK LED on the GigabitEthernet0/1

interface.

•If you have an ASA 5510, check the LINK LED on the Ethernet 1 interface.

When a connection is established, the LINK LED interface on the adaptive security appliance

and the corresponding LINK LED on the switch or hub becomes solid green.

Step 4 Launch the Startup Wizard.

a. On the PC connected to the switch or hub, launch an Internet browser.

b. In the address field of the browser, enter this URL: https://192.168.1.1/.

Note The adaptive security appliance ships with a default IP address of 192.168.1.1.

Remember to add the “s” in “https” or the connection fails. HTTPS (HTTP over SSL)

provides a secure connection between your browser and the adaptive security

appliance.

Step 5 In the dialog box that requires a username and password, leave both fields empty. Press Enter.

Step 6 Click Yes to accept the certificates. Click Yes for all subsequent authentication and certificate

dialog boxes.
