The name from the administration certificate – Select to enable redirecting to a configured domain name with a properly signed certificate. Redirecting to the name from this administration certificate is allowed when an imported certificate has been selected for HTTPS web management on that page.
This option is available only if a certificate has been imported for HTTPS management in the Web Management Settings section of the System > Administration page. Otherwise, this option is dimmed.
If you are using imported administration certificates, use this option. If you are not going to use an administration certificate, select Its configured domain name.
To do HTTPS management without the browser displaying invalid-certificate warnings, you need to import a certificate properly signed by a certification authority (administration certificate) rather than use the internally generated self-signed one. This certificate must be generated for the appliance and its host domain name. A properly signed certificate is the best way to obtain an appliance’s domain name.
If you use an administration certificate, then to avoid certificate warnings, the browser needs to redirect to that domain name rather than to the IP address. For example, if you browse the internet and are redirected to log in at
https://gateway.SonicWall.com/auth.html, the administration certificate on the appliance says that the appliance really is
gateway.SonicWall.com, so the browser displays the login page. If you are redirected to
https://10.0.02/auth.html, however, even though the certificate says it is
gateway.SonicWall.com, the browser has no way to tell if that is correct, so it displays a certificate warning instead.
