CISCO SYSTEMS Embedded BIOS Version 1.01213 082808 15:50:37.45 output omitted Step 3: Bypass setup mode. When the ASA completes the reload process, it should detect that the startup-config file is missing and go into Setup mode. If it does not come up in this mode, repeat Step 2. a. When prompted to pre-configure the firewall through interactive prompts Setup mode, respond with “no”. Pre-configure Firewall now through interactive prompts [yes]? no b. Enter privileged EXEC mode with the enable command. The password should be blank no password at this point. c. The first time you enter configuration mode after running reloading you will be asked if you wish to enable anonymous reporting. Respond with “no”. Step 4: Configure the ASA by using the CLI script. In this step you will use the modified running-config from Lab 10A to preconfigure basic settings, the firewall and DMZ.a. Other than the defaults that the ASA automatically inserts, ensure with the use of the show run
command that there is no previous configuration in the ASA. b. Enter CLI global configuration mode. When prompted to enable anonymous call-home reporting, respon d “no”. ciscoasa enable Password: enter ciscoasa conf t ciscoasaconfig c. Copy and paste the Pre-VPN Configuration Script commands listed below at the ASA global config mode prompt to bring it to the point where you can start configuring the SSL VPNs. d. Observe the messages as the commands are applied to ensure that there are no warnings or errors. If prompted to replace the RSA keypair, respond “yes”. e. Issue the write mem or copy run start command to save the running configuration to the startup configuration and the RSA keys to non-volatile memory.
