Box 1: MAC address spoofing
To enable DHCP to assign IP addresses to containers running on a Hyper-V virtual machine connected to an external switch, ensure the virtual machine's network adapter is configured to use the external switch and that the DHCP server on the network has a scope that includes the container's network. Additionally, consider enabling MAC address spoofing on the virtual machine's network adapter if needed for container networking.
Box 2: Bridge
For a Windows Server virtual machine connected to an external Hyper-V switch and provisioned for containers, the recommended network driver type for the containers is L2Bridge.
L2Bridge Driver:
This driver mode provides a Layer-2 connection between the container and the external network via the Hyper-V virtual switch. It essentially bridges the container's network traffic directly to the physical network, allowing the container to obtain an IP address from the same network as the host.
