Click Security > Certificates > Directory Servers to open the Directory Servers screen.
This screen displays a summary list of directory servers (that contain lists of valid and revoked
certificates) that have been saved into the ZyXEL Device. If you decide to have the ZyXEL
Device check incoming certificates against the issuing certification authority’s list of revoked
certificates, the ZyXEL Device first checks the server(s) listed in the
CRL Distribution
Points field of the incoming certificate. If the certificate does not list a server or the listed
server is not available, the ZyXEL Device checks the servers listed here.
