You cannot put access users and admin users in the same user group.
I cannot add the default admin account to a user group.
You cannot put the default admin account into any user group.
The schedule I configured is not being applied at the configured times.
Make sure the Zyxel Device's current date and time are correct.
I cannot get a certificate to import into the Zyxel Device.
For My Certificates, you can import a certificate that matches a corresponding certification request that
1
was generated by the Zyxel Device. You can also import a certificate in PKCS#12 format, including the
certificate's public and private keys.
You must remove any spaces from the certificate's filename before you can import 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 Zyxel Device 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 Zyxel Device.
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 Zyxel Device from a computer connected to the Internet.
Check the service control rules and to-Zyxel Device security policies.
