    Answer: If the on-premises server is reachable via VPN or ExpressRoute connection it’s possible to establish a trusted connection between them which eliminates the need to open up ports in virtual networks. This is achieved by specifying ‘valid’ certificate thumbprints during the initial connection string creation. It would be possible to use dynamic ports as well but that would mean configuring firewall rules at both ends of the VPN connection – something that may not be feasible depending upon network setup and security policies. To create a trusted connection between VMs running Azure DbContext template should also be used to define a ‘master’ SQL Server connection string.
