You must remove any spaces from the certificate's filename before you can import
2
the certificate.
Any certificate that you want to import has to be in one of these file formats:
3
• Binary X.509: This is an ITU-T recommendation that defines the formats for
X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses
lowercase letters, uppercase letters and numerals to convert a binary X.509
certificate into a printable form.
• Binary PKCS#7: This is a standard that defines the general syntax for data
(including digital signatures) that may be encrypted. A PKCS #7 file is used to
transfer a public key certificate. The private key is not included. The ZyWALL
currently allows the importation of a PKS#7 file that contains a single
certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses
lowercase letters, uppercase letters and numerals to convert a binary PKCS#7
certificate into a printable form.
• Binary PKCS#12: This is a format for transferring public key and private key
certificates.The private key in a PKCS #12 file is within a password-encrypted
envelope. The file's password is not connected to your certificate's public or
private passwords. Exporting a PKCS #12 file creates this and you must provide
it to decrypt the contents when you import the file into the ZyWALL.
Note: Be careful not to convert a binary file to text during the transfer process. It is
easy for this to occur since many programs use text files by default.
My file sharing SSL application object does not work.
Make sure you configure the shared folder on the file server to allow remote
access. Refer to the document that comes with your file server.
I cannot access the ZyWALL from a computer connected to the Internet.
Check the service control rules and to-ZyWALL firewall rules.
I uploaded a logo to display on the upper left corner of the Web Configurator login
screen and access page but it does not display properly.
Make sure the logo file is a GIF, JPG, or PNG of 100 kilobytes or less.
