To connect to an on-premises resource you'll need either an on-premises gateway or the IP address will need to be published to an internet accessible IP address.  The 192.168 range you are using is a private range that only works within a Local area network.  I doubt that business central on your machine has an Internet Accessible address.  So you'll need a gateway.
