It's working properly. Your cisco VPN client has been configured to
prevent split tunnelling (send traffic to different destinations
depending on the endpoint)

It is a security risk to allow users to connect to both the secure
network and an unsecure network at the same time. Someone could hack
into your system from the unsecured side to piggyback through to the
secure network.
