PKI Storage 
Space in Use

This bar displays the percentage of the ZyWALL’s PKI storage space that is 
currently in use. When the storage space is almost full, you should consider 
deleting expired or unnecessary certificates before adding more certificates.

Replace

This button displays when the ZyWALL has the factory default certificate. The 
factory default certificate is common to all ZyWALLs that use certificates. ZyXEL 
recommends that you use this button to replace the factory default certificate with 
one that uses your ZyWALL's MAC address.

#

This field displays the certificate index number. The certificates are listed in 
alphabetical order. 

Name

This field displays the name used to identify this certificate. It is recommended that 
you give each certificate a unique name. 

Type

This field displays what kind of certificate this is. 
REQ represents a certification request and is not yet a valid certificate. Send a 
certification request to a certification authority, which then issues a certificate. Use 
the My Certificate Import screen to import the certificate and replace the request.
 SELF represents a self-signed certificate. 
*SELF represents the default self-signed certificate, which the ZyWALL uses to 
sign imported trusted remote host certificates.

Subject

This field displays identifying information about the certificate’s owner, such as CN 
(Common Name), OU (Organizational Unit or department), O (Organization or 
company) and C (Country). It is recommended that each certificate have unique 
subject information.
