1.  INSTALL NOTES

    1.1 Entering New Activation Codes
    
        If upgrading from 3.7.3 or below, new activation codes must be
        entered. GB-OS version 4.0.3 is available at no charge to
        customers with a GTA support contract or annual maintenance
        agreement, or for customers with a GTA firewall operating on 
        GB-OS version 4.0.0. Other users should contact their local 
        GTA channel partner or email sales@gta.com for information and
        pricing of upgrade options.
        
    1.2 Upgrading from GB-OS 3.5 or Below
    
        If upgrading from GB-OS 3.5 or below, it is necessary to first
        upgrade to an interim version of GB-OS before installing GB-OS
        4.0.  For upgrade instructions, refer to Reference D in the
        GB-OS User's Guide.

    1.3 Upgrading Hard Drive GB-Ware Installations from 3.5.x to 4.0.3

        When upgrading a hard drive GB-Ware firewall from version 3.5.x 
        to 4.0.3:

            1.  Back up the firewall configuration.
            2.  Reinstall the firewall software completely from the CD.
            3.  Restore the configuration.

        The GB-Ware CD image (ISO-9660) is available for download from 
        GTA's Online Support Center 
        (https://www.gta.com/support/center/login/). Failure to reinstall
        from CD may cause hard drive geometry errors that prevent the 
        upgrade.
        
    1.4 Upgrading from GB-OS 3.7.2 and Below    
        
      1.4.1 Error Messages Upon Initial Reboot
    
            Upon rebooting after successful installation, the GTA
            firewall may display errors when accessed using the Web
            interface. This is expected, these errors are generated
            because the browser's cache is trying to access files and
            locations that no longer apply. Click OK to any displayed
            errors and refresh the browser window to access GB-OS 4.0.
            If the error messages persist, clear your browser's cache.
        
      1.4.2 Default Login and Password Changes
        
            Firewall administrators who have never changed their default
            login and password in the Admin Accounts section of GB-OS
            3.x will find that their default account's login information
            will no longer work with GB-OS 4.0.  After the firewall
            administrator has upgraded to GB-OS 4.0, their login and
            password will both default to "fwadmin".
            
      1.4.3 User Group Assignments When Upgrading From Previous Versions
    
            When upgrading to GB-OS 4.0.3, users will automatically be
            organized into groups based on the name of the their VPN
            object. For example, a user that made use of a VPN object
            with a name of Marketing Department will be assigned to a
            group named Marketing Department, while a user that made use
            of a VPN object with the name of MOBILE will be assigned to
            a group named MOBILE.
            Users that have no VPN object assigned to them will be
            organized into groups based on the GB-OS version that the
            administrator is upgrading from, such as Users_372.
            
      1.4.4 Static Gateway to Static Gateway VPN Failure
    
            Firewall administrators that have a configured VPN between
            two static gateways may find that their VPN no longer
            functions after they have upgraded to GB-OS 4.0.  This is
            caused when the firewall administrator had a local identity
            configured in the Authorization>VPN section on their GTA
            firewall before it was upgraded to GB-OS 4.0.  GB-OS
            versions prior to GB-OS 4.0 ignored this field when a static
            gateway to static gateway VPN was configured; in GB-OS 4.0,
            the local identity is recognized and can result in a failure
            when a VPN connection previously worked. To correct this
            issue, simply navigate to Configuration>VPN>IPSec Tunnels
            and edit the IPSec tunnel in question by setting the local
            identity to IP Address. 
            
      1.4.5 Restrictive VPN Configurations
    
            When upgrading to GB-OS 4.0, firewall administrators may
            need to rebuild their VPN policies.  In previous versions of
            GB-OS, VPN access was controlled using pass through filters.
            In GB-OS 4.0, VPN access is controlled using VPN policies
            which allow all VPN traffic by default. Firewall
            administrators who have upgraded to GB-OS 4.0 will need to
            manually recreate any restrictive VPN policies.
            
      1.4.6 VPN Object Names
    
            Previously defined VPN objects will have the GB-OS version
            number appended to their name after the GTA firewall has
            been upgraded to version 4.0.  For example, a VPN object
            with a name of IKE in GB-OS 3.7.0 will be named IKE_370
            after the upgrade.
            
      1.4.7 Address Object Identification

            Previously defined address objects that were of type IP
            Addresses will be re-categorized as being of type All after
            the GTA firewall has been upgraded to version 4.0.
            
    1.5 Upgrading from GB-OS 4.0.0 or 4.0.1
    
      1.5.1 Service Group Object Modifications
          
          The built-in DNS Zone service group object has been merged
          with the DNS Lookups service group object.  Because of this
          merger, configurations that reference the now defunct DNS Zone
          service group object will need to be updated to reference the 
          DNS Lookups service group object.    
        
    1.6 Platform Independent Web Interface
    
        GB-OS 4.0 includes a platform independent web interface which
        provides an improved workflow, user-friendly design with
        enhanced features such as offline configuration and verification
        using GB-OS 4.0's Test Mode. GBAdmin is not supported by
        GB-OS 4.0.

    1.7 SSL Certificate Replacement

        GB-OS version 4.0.3 will install a new default security/SSL
        certificate. Some browsers, including Netscape and Mozilla,
        will not recognize the new certificate if the original has
        never been replaced. If you are unable to log on to the
        firewall after upgrading, delete the browser's cached security
        certificate, then close and restart your browser before
        reattempting remote access to your firewall.
