Click 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 ZyWALL. If you decide to have the ZyWALL check incoming certificates against the issuing
certification authority’s list of revoked certificates, the ZyWALL 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 ZyWALL checks the servers listed here.
