25.2.1 About the Certificate Not Trusted Log

myZyXEL.com and the update server use certificates signed by VeriSign to identify themselves. If the ZyWALL does not have a CA certificate signed by VeriSign as a trusted CA, the ZyWALL will not trust the certificate from myZyXEL.com and the update server. The ZyWALL will generate a log like "Due to error code(11), cert not trusted: SSL/TLS peer certif..." for every time it attempt to establish a (HTTPS) connection with myZyXEL.com and the update server. The V4.00 default configuration file includes a trusted CA certificate signed by VeriSign. If you upgraded to ZyNOS V4.00 firmware without uploading the V4.00 default configuration file, you can download a CA certificate signed by VeriSign from myZyXEL.com and import it into the ZyWALL as a trusted CA. This will stop the ZyWALL from generating this log every time it attempts to connect with myzyxel.com and the update server.
