Q1: Can VM1 and VM2 communicate with each other?
A1: Yes, they can, as long as they are using the same VLAN ID and the Hyper-V virtual switch is also configured with the same VLAN ID (Access Mode) or configured in the Trunk Mode.
Q2: Can VM3 communicate with VM1 or VM2?
A2: No. VM3 is configured with a VLAN ID 5, but the virtual switch (vSwitch1) can only accept network packets that are tagged with VLAN ID 4. So, to allow communication between all virtual machines (VM1, VM2 and VM3 in this example), vSwitch1 must be configured in the Trunk Mode. In other words, you must uncheck the "Enable VLAN identification for management operating system" setting.
Q3: How can we restrict communication between VM1 and VM3 and at the same time allow VM2 to communicate with a server on an external LAN?
A3: To restrict communication between VM1 and VM3, you must configure VM1 and VM3 with the same VLAN ID and then configure vSwitch1 in Trunk Mode. This configuration will force vSwitch1 to receive all network packets from all the virtual machines connected to it.
