This method is called
only if you have implemented the
IwodVPNNotify interface in your
application and the wodVPN1.Notification
property has received a reference to an instance of your implementation.
UserConnected notification method is called after you have allowed user to connect and use channel they have chosen. From this point, user will be communicating with remote service through encrypted channel.
There will be no further interference between wodVPN and the user - all his data will be forwarded to remote wodVPN peer, and vice versa. When user disconnects,
UserDisconnected notification method will be called.
