              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 6.1.11. If the error messages persist, clear your
              browser's cache.

              SHA-2, with keys larger than 128, will need to be upgraded. 
              If unable to upgrade, firewalls must be switched to a compatible 
              algorithm.
              
        1.2.5 Web Filtering Upgrade Notice
      
              GB-OS 6.1.3 and above includes enhancements to the Web Filtering
              category listings. The Web Filtering categories will be modified 
              when your GTA firewall is updated to GB-OS 6.1.11. Existing Web 
              Filtering categories will be automatically mapped to the enhanced 
              categories included in GB-OS 6.1.11. 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.

    1.3 SSL Certificate Replacement

        GB-OS version 6.1.11 and above 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
