NBG410W3G Series User’s Guide

• 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 

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 
192.168.1.1, 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. 

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.

Click Login and you then see the next screen.
The factory default certificate is a common default certificate for all ZyXEL Device models.
