As per security concern, need to restrict/block the dbricks workspace url outside the corporate network. Tried below ip access list, it able to restrict only user login access out the corporate network but still the workspace id url is live outside the corporate network.

Can anybody advise how to block the workspace url outside the network? Also other requirement is require to block data brick spark UI ?
