The standard connection will only be automatically re-established after a backup event if the hold time for the connection is configured properly:
- A hold time of "0" means that the connection will not be actively terminated. If the connection is interrupted, it will not be automatically established again. Only when communication is required of the connection will it be established.
- A hold time of "9999" means that the connection is permanently kept open. If it is interrupted, then the connection will be actively opened up again. This behavior is known as keep alive.
Set the hold time to "9999" for connections to the Internet provider (in the corresponding peer list) and backed-up VPN connections (in the VPN connection list) to ensure that the connection is automatically re-established and resumes data transfer after interruption.
