• 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 D on page 289 for details.

• The actual IP address of the HTTPS server (the IP address of the ZyXEL Device’s port

that you are trying to access) does not match the common name specified in the ZyXEL

Device’s HTTPS server certificate that your browser received. Do the following to check

the common name specified in the certificate that your ZyXEL Device sends to HTTPS

clients.

2a Click REMOTE MGMT. Write down the name of the certificate displayed in the

Server Certificate field.

2b Click CERTIFICATES. Find the certificate and check its Subject column. CN

stands for certificate’s common name (see Figure 95 on page 162 for an example).

Use this procedure to have the ZyXEL Device use a certificate with a common name that

matches the ZyXEL Device’s actual IP address. You cannot use this procedure if you need to

access the WAN port and it uses a dynamically assigned IP address.

2a Create a new certificate for the ZyXEL Device that uses the IP address (of the

ZyXEL Device’s port that you are trying to access) as the certificate’s common

name. For example, to use HTTPS to access a LAN port with IP address

192.168.1.2, create a certificate that uses 192.168.1.2 as the common name.

2b Go to the remote management WWW screen and select the newly created certificate

in the Server Certificate field. Click Apply.

13.9.4 Login Screen

After you accept the certificate, the ZyXEL Device login screen appears. The lock displayed

in the bottom right of the browser status bar denotes a secure connection.
