  • Cisco ASA 5505

    Hi Guys

    I have a Cisco ASA 5505 Firewall and i just factory reset the device and blanked the password so i can connect via cli and ASDM, when i 'config factory-default' and the renew my IP i have Internet access via the default setup of WAN (Outside) DHCP connection but as soon as i try save my config (type ‘reload save-config noconfirm’) my device reboots and loses all config anyone any ideas on what im doing wrong? I have also tried 'write mem' before the above reload save command but that doesnt seem to save the config either?

    Any help much appreciated

    below are the steps i have followed in red.

    After you open your hyperterminal connection, press enter a couple times, and you should get a prompt like: ‘ciscoasa>’, or ‘nameofyourdevice>’

    type ‘ena’ to go to enable mode.
    Enter the password, or just press enter if there is no password set.

    type ‘config t’

    type ‘config factory-default’

    hit spacebar when the ‘more’ thing happens.
    You want to get back to the prompt that looks like: ‘ciscoasa(config)#’

    type ‘reload save-config noconfirm’

    make sure that the outside line is plugged into port zero, and your pc is plugged into any of the ports 1-7.

    The Cisco ASA has been reset to factory settings. DHCP is enabled on the cisco device, and it’s internal IP address is now 192.168.1.1!

      In the show version look at the config-register (Towards the bottom of the show version output)


      This value should be 0x1

      If its different change it to 0x1

      config-register 0x1


      Then do config factory-default

      write mem

      reload

          Fair play Auglan

          That fixed my issue perfectly, now it holds the config through a reboot

          What was causing the issue?

            0x41 is used for password recovery on the asa. On boot up it ignores the startup configuration file.

            0x1 tells the asa to load the saved configuration

            Was this a used asa? If so the old user set it to 0x41 to blow out the password etc but forgot to switch it back to 0x1.
