NBG410W3G Series User’s Guide

After you click Apply in the My Certificate Create screen, you see a screen that tells you the 
ZyXEL Device is generating the self-signed certificate or certification request. 
After the ZyXEL Device successfully enrolls a certificate or generates a certification request 
or a self-signed certificate, you see a screen with a Return button that takes you back to the 
My Certificates screen.
If you configured the My Certificate Create screen to have the ZyXEL Device enroll a 
certificate and the certificate enrollment is not successful, you see a screen with a Return 
button that takes you back to the My Certificate Create screen. Click Return and check your 
information in the My Certificate Create screen. Make sure that the certification authority 
information is correct and that your Internet connection is working properly if you want the 
ZyXEL Device to enroll a certificate online.

Click SECURITY > CERTIFICATES > Trusted CAs to open the Trusted CAs screen. This 
screen displays a summary list of certificates of the certification authorities that you have set 
the ZyXEL Device to accept as trusted. The ZyXEL Device accepts any valid certificate 
signed by a certification authority on this list as being trustworthy; thus you do not need to 
import any certificate that is signed by one of these certification authorities. 

RA Signing Certificate If you select Enrollment via an RA, select the CA’s RA signing certificate from 

the drop-down list box. You must have the certificate already imported in the 

Trusted CAs screen.
Click Trusted CAs to go to the Trusted CAs screen where you can view (and 

manage) the ZyXEL Device's list of certificates of trusted certification 

authorities.
