On the Server:

  • Add a "Bridged VNet - Device"

"Bridged networking (also known as network bridging or virtual network switching) will place virtual machine network interfaces on the same network as the physical interface. Bridges require minimal configuration and make a virtual machine appear on an existing network, which reduces management overhead and network complexity"

Depending on the platform (Hyper-V, VMware Workstation or vSphere), the procedure for this will look different and is not covered in this article.

  • Add a Host Only VNet - Device

A host-only network has a network interface associated with it, that is marked up when the host operating system is booted. Routing server processes that operate on the host operating system automatically discover the host-only network and propagate information on how to reach the network, unless you explicitly configure them not to do so.
