Note: You can import a certificate that matches a corresponding certification request
that was generated by the ZyWALL. You can also import a certificate in
PKCS#12 format, including the certificate’s public and private keys.
The certificate you import replaces the corresponding request in the
My

screen.
You must remove any spaces from the certificate’s filename before you can import
it.

screen. This screen displays a summary list of certificates
that you have set the ZyWALL to accept as trusted. The ZyWALL also accepts any
valid certificate signed by a certificate on this list as being trustworthy; thus you
do not need to import any certificate that is signed by one of these certificates.
