This will depend on the configuration pushed by the administrator. The admin can enforce either full tunnel or split tunnel.
If you are trying to reach a local subnet and it is going through the tunnel, it is likely enforced by the administrator to not allow access to the local subnet.
To confirm this scenario, you can run a "route print" and see where the 192.168.1.x route is pointed to. If it is not mentioned, then it will fall under 0.0.0.0 which is likely pointed to the tunnel interface. If local subnet is required, then discussion with the admin would be needed to see if an exception can be made.
