43.7.7.3 Avoiding Browser Warning Messages
Here are the main reasons your browser displays warnings about the ZyWALL/USG's HTTPS server
certificate and what you can do to avoid seeing the warnings:
• The issuing certificate authority of the ZyWALL/USG's HTTPS server certificate is not one of the
browser's trusted certificate authorities. The issuing certificate authority of the ZyWALL/USG's
factory default certificate is the ZyWALL/USG 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.
43.7.7.4 Login Screen
After you accept the certificate, the ZyWALL/USG login screen appears. The lock displayed in the
bottom of the browser status bar denotes a secure connection.
