I changed the LAN IP address and can no longer access the Internet.
The Zyxel Device automatically updates address objects based on an interface's IP address, subnet, or
gateway if the interface's IP address settings change. However, you need to manually edit any address
objects for your LAN that are not based on the interface.
I configured application patrol to allow and manage access to a specific service but access is
blocked.
If you want to use a service, make sure the security policy allows Security Service application patrol to
go through the Zyxel Device.
My two-factor authentication is not working.
Check that match the specifications and limitation in the following list:
• Ext-users (authenticated by external servers) are not supported.
• You must setup Google Authenticator on their mobile device before you can successfully
authenticate with the Zyxel Device.
I get a Google Authenticator verification error.
• Check that you enter the right verification code. The verification code should be 6 digits.
• You must enter the code within the time displayed in Google Authenticator.
• You've exceeded the maximum verification code failed attempts.
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.
