Being used to VMware Workstation, where NATing is a few GUI clicks away, I couldn’t find a GUI way of configuring it in Hyper-V.
inside local outside hokey pokey; Turn yourself around
I don’t mind the command line and actually prefer it sometimes. The PowerShell equivent didn’t end up being too bad. Not like the first time doing Cisco NAT from the CLI 🙂
Setting up NAT
The first code block is the generic commands from the Microsoft reference document the second one is what I used in my lab.
# Create Internal vSwitch for NAT New-VMSwitch -SwitchName "SwitchName" -SwitchType Internal # Configure the NAT gateway New-NetIPAddress -IPAddress <NAT Gateway IP> -PrefixLength <NAT Subnet Prefix Length> -InterfaceIndex <ifIndex> # Configure the NAT network New-NetNat -Name <NATOutsideName> -InternalIPInterfaceAddressPrefix <NAT subnet prefix>
New-VMSwitch –SwitchName “NATvSwitch” –SwitchType Internal New-NetIPAddress –IPAddress 220.127.116.11 -PrefixLength 24 -InterfaceAlias "vEthernet (NATSwitch)" New-NetNat –Name myNATnetwork –InternalIPInterfaceAddressPrefix 18.104.22.168/24
Windows (WinNAT) only supports one internal NAT subnet prefix, trying to create multiple NATs will place the system into an unknown state. 1.
