Last night, one of the the systems administrator had to re-index a database, which takes about 3 hrs to do. Yet, stubborn users (local and remote) still try to log on to the database to input data, even though a notice was sent out for them not to log on. So, to stop the remote users, I shutdown the port on the core switch where the the public interface of the Cisco VPN concentrator (3015) connects to. Thus, disconnecting any user. But to my surprise, one user was able to VPN in and log on to the server. So I shutdown the port where the private interface of the VPN concentrator connects in the core switch. That disconnect the user. So now both the private and public interfaces of the VPN concentrator where shutdown. But how could this user have still be able to VPN into the network, when the public interface of the concentrator was shutdown?
