#requires -Version 3.0 -Modules Hyper-V, NetAdapter, NetNat, NetTCPIP, Storage <# .Synopsis This module lets you roll out your lab environment automatically. This is the first step: creating a NATSwitch. .DESCRIPTION This module lets you roll out your lab environment automatically as described in our blogs (www.365dude.nl and www.svenvanrijen.nl). This is the first step: creating a NATSwitch. The Name parameter is mandatory. IP Address is optional, "172.16.10.1" is the default value. Prefix Length is optional, "24" is the default value. NAT name is optional, "LABnat" is the default value. .EXAMPLE You first have to create a NATSwitch, before creating any VM's in your lab. New-NATswitch -Name NATswitch creates a NATswitch with the default IP Address (172.16.10.1), Prefix Length (24) and NAT name (LABnat) .EXAMPLE New-NATSwitch -Name Test -IPAddress 10.0.1.1 -PrefixLength 24 -NATName TestNAT With this line of code you create a new VMSwitch within HyperV with the name Test. Also an IP Address (10.0.1.1) is assigned to this switch and a NAT network with address space 10.0.1.0/24 is created. #> function New-NATSwitch { [CmdletBinding()] [OutputType([String])] Param ( [Parameter(Mandatory = $true)] [string]$Name, [Parameter(Mandatory = $false)] [string]$IPAddress = 172.16.10.1, [Parameter(Mandatory = $false)] [int]$PrefixLength = 24, [Parameter(Mandatory = $false)] [string]$NATName = 'LabNAT' ) Begin { } Process { New-VMSwitch -SwitchName $Name -SwitchType Internal $NetAdapter = Get-NetAdapter -Name "vEthernet ($Name)" $InterfaceIndex = $NetAdapter.ifIndex New-NetIPAddress -IPAddress $IPAddress -PrefixLength $PrefixLength -InterfaceIndex $InterfaceIndex $ip2 = $IPAddress.Split('.') $ip2[-1] = "0/$PrefixLength" $InternalIPInterfaceAddressPrefix = $ip2 -join '.'

This is the second step: creating a Lab VM's. .DESCRIPTION This module lets you roll out your lab environment automatically as described in our blogs (www.365dude.nl and www.svenvanrijen.nl). This is the second step: creating a Lab VM's. First step: creating a NATSwitch (New-NATSwitch). New-LabVM generates a new VM in the lab environment. IPAddress is a mandatory parameter and must be in the "172.16.10.10/24" notation. Please use the same address space as used when creating the NATSwitch. The specification of a Gateway is optional. If DNS-server is not specified, the default will be used. (172.16.10.1) The specification of a DNS-server is optional. If DNS-server is not specified, the default will be used.
