New-AzVirtualNetworkGateway - Public IP address referecne is required

[Florian Adler]

Hi all,

I'm currently trying to create an AVD environment with nearly all required infrastructure via PowerShell: VNETs, Host Pools, etc. Right now I'm stuck at the creation step of the VPN Gateway. Feel free to take a look:

## Networking
# SubNets
$subnetDEVconfig = @{
    Name = 'DevSubnet'
    AddressPrefix = '10.0.1.0/24'
}

$subnetPRODconfig = @{
    Name = 'ProdSubnet'
    AddressPrefix = '10.0.2.0/24'
}

$subnetGatewayconfig = @{
    Name = 'GatewaySubnet'
    AddressPrefix = '10.0.0.0/27'
}

# VNET
$vnetconfig = @{
    Name = 'VNET-AVD'
    ResourceGroupName = $RGWVDEnv
    Location = $locationGen
    AddressPrefix = '10.0.0.0/20'    
    Subnet = $subnetDEVconfig,$subnetPRODconfig,$subnetGatewayconfig
}

Write-Host -ForegroundColor Green "Creating VNET"$vnetconfig.Name"with subnets"$subnetDEVconfig.Name","$subnetPRODconfig.Name"and"$subnetGatewayconfig.Name
$virtualNetwork = New-AzVirtualNetwork @vnetconfig
$virtualNetwork = Get-AzVirtualNetwork -Name $vnetconfig.Name -ResourceGroupName $RGWVDENV

## VPN
# Public IP
Write-Host -ForegroundColor Green "Creating VPN Gateway"
$gwpipconfig = @{
    Name = 'Gateway-PIP-001'
    ResourceGroupName = $RGGeneral
    location = $locationGen
    AllocationMethod = 'static'
}

New-AzPublicIpAddress @gwpipconfig

$gwvnet = Get-AzVirtualNetwork -Name $vnetconfig.Name -ResourceGroupName $RGWVDEnv
$gwsubnet = Get-AzVirtualNetworkSubnetConfig -Name $subnetGatewayconfig.Name -VirtualNetwork $gwvnet
$gwpipassign = New-AzVirtualNetworkGatewayIpConfig -Name 'GW-PIP-Config-001' -SubnetId $gwvnet.subnets[2].Id -PublicIpAddressId $gwpipconfig.Id

# Gateway
$gwconfig = @{
    Name = 'AVD-VPN-Gateway-001'
    ResourceGroupName = $RGGeneral
    Location = $locationGen
    IpConfigurations = $gwpipassign
    GatewayType = 'VPN'
    VpnType = 'RouteBased'
    GatewaySku = 'Basic'
}

New-AzVirtualNetworkGateway @gwconfig

Running this results in the following error message I can't explain:

New-AzVirtualNetworkGateway: Public IP address reference is required for gateway IP configration /subscriptions/<<SUB-ID>>/resourceGroups/AVD-General-Services/providers/Microsoft.Network/virtualNetworkGateways/AVD-VPN-Gateway-001.

Does anyone can give me a hint, what I may have missed? As a source for the above snippet, I also used this: https://docs.microsoft.com/en-us/powershell/module/az.network/new-azvirtualnetworkgateway?view=azps-...

Hmm, take a look at this for reference:

Looks quite familiar with the Microoft Docs reference.

Meanwhile I found the missing part: Instead of New-AzPublicIpAddress @gwpipconfig I had to type $gwpipconfig = New-AzPublicIpAddress @gwpipconfig. Otherwise any new parameter would get lost and not be available in the variable. Small mistake but bit issue.
