              GB-250 Rev A firewalls are NOT supported in GB-OS 6.1.0 and above.
              Determine GB-250 Rev A or Rev B by the following:
              
                 1. GB-250 Rev B firewalls have USB ports while GB-250 Rev A do
                    not have USB ports. 
              
                 3. GB-250 Rev B firewall serial numbers are:

        1.2.3 Error Messages Upon Initial Reboot
    
              Upon rebooting after successful installation, the GTA
              Firewall UTM Appliance 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 6.2.0. If the error messages persist, clear your
              browser's cache.

              category listings. The Web Filtering categories will be modified 
              when your GTA firewall is updated to GB-OS 6.2.0. Existing Web 
              Filtering categories will be automatically mapped to the enhanced 
              categories included in GB-OS 6.1.4. Please review the Content 
              Filtering Feature Guide for details on the Web Filtering 
              category mapping.
            
              GTA strongly recommends reviewing the settings for all (new and 
              automatically mapped) categories and making any necessary 
              revisions to your Web Filtering settings and policies to ensure 
              they meet your corporate Internet Access Policy.

              GTA strongly recommends reviewing the settings for all enabled

              to ensure they meet your corporate Internet Access Policy.

        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
