Chapter 51 Troubleshooting

I cannot get a certificate to import into the ZyWALL.

1For My Certificates, 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.

2You must remove any spaces from the certificate’s filename before you can import the certificate.

3Any certificate that you want to import has to be in one of these file formats:

•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.

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.
