• After you click Apply in the My Certificate Create screen, you see a screen that tells you 

the ZyWALL is generating the self-signed certificate or certification request. 

• After the ZyWALL 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 ZyWALL 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 ZyWALL 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 ZyWALL to accept as trusted. The ZyWALL 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 ZyWALL's list of certificates of trusted certification authorities.

Authentication

certification authority uses CMP enrollment protocol. Just fill in the Key field if
