• 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 J on page 847 for details.
• The actual IP address of the HTTPS server (the IP address of the ZyWALL’s port that you
are trying to access) does not match the common name specified in the ZyWALL’s
HTTPS server certificate that your browser received. Do the following to check the
common name specified in the certificate that your ZyWALL 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 284 on page 494 for an example).
Use this procedure to have the ZyWALL use a certificate with a common name that matches
the ZyWALL’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 ZyWALL that uses the IP address (of the
ZyWALL’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 192.168.1.1,
create a certificate that uses 192.168.1.1 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.
26.4.4 Login Screen
After you accept the certificate, the ZyWALL login screen appears. The lock displayed in the
bottom right of the browser status bar denotes a secure connection.
Figure 282 Example: Lock Denoting a Secure Connection
Click Login and you then see the next screen.
The factory default certificate is a common default certificate for all ZyWALL models.
