Upon each Windows startup, Kerio VPN Client attempts to recover persistent connections. The following rules are applied:
If Kerio VPN Client was closed in the simple mode, it will attempt to open the connection defined in the simple mode dialog window (if the Persistent connection and Connect automatically options are enabled — see chapter 2.2 Kerio VPN Client in the simple mode).
If Kerio VPN Client was exited in the advanced mode, it will attempt to recover all VPN connections defined in the advanced mode dialog box for which the automatic persistent connection is enabled (see chapter 2.3 Kerio VPN Client in the advanced mode).
If no automatic persistent connection is defined in a current mode, Kerio VPN Client will be closed (users can start it by hand).
This implies that it is quite important under which mode Kerio VPN Client is closed. Therefore, it is recommended to use only one mode.
