1.  INSTALL NOTES

    1.1 Entering New Activation Codes
    
        If upgrading from 3.6.2 or below, new activation codes must be
        entered. GB-OS version 3.7.1 is available at no charge to
        customers with a GTA support contract or annual maintenance
        agreement, or who purchased a GTA firewall operating on GB-OS
        version 3.7.0. Other users should contact their local GTA
        channel partner or email sales@gta.com for information and
        pricing of upgrade options.

    1.2 Upgrading Hard Drive GB-Ware Installations from 3.5.x to 3.7.1

        When upgrading a hard drive GB-Ware firewall from version 3.5.x 
        to 3.7.1:

            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.

    1.3 SSL Certificate Replacement

        Version 3.7.x 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.
