15.4.5.3 Avoiding Browser Warning Messages
Here are the main reasons your browser displays warnings about the Zyxel Device’s HTTPS server
certificate and what you can do to avoid seeing the warnings:
• The issuing certificate authority of the Zyxel Device’s HTTPS server certificate is not one of the browser’s
trusted certificate authorities. The issuing certificate authority of the Zyxel Device's factory default
certificate is the Zyxel Device itself since the certificate is a self-signed certificate.
• For the browser to trust a self-signed certificate, import the self-signed certificate into your operating
system as a trusted certificate.
• To have the browser trust the certificates issued by a certificate authority, import the certificate
authority’s certificate into your operating system as a trusted certificate. Refer to Appendix A on
page 216 for details.
15.4.5.4 Enrolling and Importing SSL Client Certificates
The SSL client needs a certificate if Authenticate Client Certificates is selected on the Zyxel Device.
You must have imported at least one trusted CA to the Zyxel Device in order for the Authenticate Client
Certificates to be active (see the Certificates chapter for details).
Apply for a certificate from a Certification Authority (CA) that is trusted by the Zyxel Device (see the
Zyxel Device’s Trusted Certificates Web Configurator screen).
