The wizard will not allow you to continue without entering a DMZ address. To do so see the following article: Using DDNS Services with SBS 2008/2011 When using DHCP you will probably also want to set up a DDNS service. If using DHCP with your ISP, select вЂњUse DHCPвЂќ and check вЂњObtain default route using DHCPвЂќ (which will automatically add the default gateway). (Note: you will need to add a static route for the default gateway later) If so select вЂњUse the following IP addressвЂќ, enter the appropriate IP and subnet mask under вЂњOutside AddressвЂќ. Interface IP Address Configuration: Presumably you have been assigned a static public IP by your ISP where you are running a mail server. Switch Port Allocation: Again the defaults are fine for this configuration. When you log back in later the user name will still be blank. I strongly recommend changing the password, and make it secure. Starting Point: In the first window accept the default вЂњmodify existing configurationвЂќ and click next.Д«asic Configuration: If you like you can change the ASA Host Name and domain, but I is not necessary. You can also start the wizard from within the ASDM from the menu under Wizards, Startup Wizard.

When prompted for a username and password leave both blank. Launch the ASDM using, choose to ignore the certificate error, and select вЂњrun Startup WizardвЂќ. During the process do not make changes to the internal interface IP or Internal DHCP settings. We will run the Start up Wizard to do the basic configuration.

the unit will reboot with factory defaults.

reload save-config noconfirm (to write to flash memory).

config factory-default (press the space bar a few times when вЂњmoreвЂќ is displayed to get back to the prompt).

Once connected to the CLI (Command Line Interface) enter the following commands:

you do not know the IP, you can use the blue console cable and access through Telnet. If you do not have access to the ASDM console, i.e. Since this article is dedicated to using the ASDM console, to reset from within, simply log on, select вЂњFileвЂќ from the menu, and then вЂњReset Device to the Factory Default ConfigurationвЂќ.

If so, skip to вЂњBasic Router configurationвЂќ. It is assumed the ASA is still set to factory defaults.

I will however post a follow-up article outlining how to do so from the CLI, using only a handful of commands. For the record this can be accomplished much more easily from the CLI/Command Line Interface, but we SBS folk tend to like to do things from a GUI. The ASDM version used at the time of writing is 6.4(5), and ASA Version 8.2(5). Following is an outline as to how to configure a Cisco ASA 5505 for an SBS 2008/2011 network, including basic router configurations, IP addressing, and port forwarding, using the GUI/ASDM.
