My Windows 11 Pro Workstation uses Hyper-V and I have a external virtual switch (TGN-External) and virtual interface (vEthernet (TGN-External)) that gets an IP via DHCP on the network
I want to assign another secondary IP address (192.168.1.2) so I can connect to a pfsense netgate appliance
Going into the vEthernet (TGN-External) interface in the GUI and assigning an Alternative Configuration didn't work
I had to add a second vEthernet (Hyper-V Virtual Ethernet Adapter #4) and then assign it an IP vEthernet (PFSENSEIP)
Add-VMNetworkAdapter -ManagementOS -Name PFSENSEIP -SwitchName TGN-External
# to see interface index
Get-NetAdapter
# assign the ip
New-NetIPAddress -InterfaceIndex 9 -IPAddress 192.168.1.2 -PrefixLength 24
If you need to remove multiple bad attempts, or remove the interface when finished, you can use the following snippet
Get-VMNetworkAdapter -ManagementOS -Name PFSENSEIP | Remove-VMNetworkAdapter
Get the adaptors linked to the Mangement OS
Get-VMNetworkAdapter -ManagementOS
Name IsManagementOs VMName SwitchName MacAddress Status IPAddre
