• 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.
a Click REMOTE MGMT . Write down the name of the certificate
displayed in the Server Certificate field.
b Click CERTIFICATES . Find the certificate and check its Subject
column. CN stands for certificate’s common name ( Figure 94 on page
199 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.
a 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 192.168.167.1, create a certificate that uses
192.168.167.1 as the common name.
b Go to the remote management WWW screen and select the newly
created certificate in the Server Certificate field. Click Apply .
13.4.4 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.
