I have hunted around for an answer to this, but I am not having much luck. All the articles I can find are either setting up a Point-to-Site or are instructions for classic Azure, not Azure 2.0 (Resource Group)
Currently, we are dialing up a whole new resource group everytime we do a new built. This consists of Web apps and SQL DBs. When we have a new build we start up the new and del the old resource group. Simple. To minimize the start-up time we have a static resource group that isn't deleted that houses the VPN connection to our on Prem resources.
The problem I'm having is when I add the new websites using AzureRM Powershell cmd's to the Point-to-site it says it's successful. The Azure Portal says its good but it does let me communicate. If I remove and add it from one of the 8 WebApps they all start working.
I am out of ideas. Any help would be greatly appreciated.
Azure VPN
Below is the function I have put togeather from what I can find out there.
function AddExistingVnet{
param(
[string] $subscriptionId,
[string] $resourceGroupName,
[string] $webAppName
)
$Vnet = Get-AzureRmVirtualNetwork | Where-Object {$_.ResourceGroupName -like "*Static*"}
IF($Vnet.Name.count -gt 1) {write-host 'Two or networks have been returned. Unable to continue ' return}
$gatewaySubnet = $vnet.Subnets | Where-Object { $_.Name -eq "GatewaySubnet" }
$vnetName = $vnet.Name
$uriParts = $gatewaySubnet.IpConfigurations[0].Id.Split('/')
$gatewayResourceGroup = $uriParts[4]
$gatewayName = $uriParts[8]
$gateway = Get-AzureRmVirtualNetworkGateway -ResourceGroupName $vnet.ResourceGroupName -Name $gatewayName
Write-Host "Creating App association to VNET"
$propertiesObject = @{
"vnetResourceId" = "/subscriptions/$($subscriptionId)/resourceGroups/$($vnet.ResourceGroupName)/providers/Microsoft.Network/virtualNetworks/$($vnetName)"
}
$virtualNetwork = New-AzureRmResource -Location $location -Properties $PropertiesObject -ResourceName "$($webAppName)/$($vnet.Name)" -ResourceType "Microsoft.Web/sites/virtualNetworkConnections" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName -Force
# Now finish joining by getting the VPN package and giving it to the App
Write-Host "Retrieving VPN Package and supplying to App"
$packageUri = Get-AzureRmVpnClientPackage -ResourceGroupName $vnet.ResourceGroupName -VirtualNetworkGatewayName $gateway.Name -ProcessorArchitecture Amd64
# Put the VPN client configuration package onto the App
$PropertiesObject = @{
"vnetName" = $vnet.Name; "vpnPackageUri" = $packageUri
}
New-AzureRmResource -Location $location -Properties $PropertiesObject -ResourceName "$($webAppName)/$($vnet.Name)/primary" -ResourceType "Microsoft.Web/sites/virtualNetworkConnections/gateways" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName -WarningAction silentlyContinue -Force
}
So after 2 weeks of going back and forth with Microsoft (had a really good guy Charles) we managed to find the problem.
When requesting
$packageUri = Get-AzureRmVpnClientPackage -ResourceGroupName $vnet.ResourceGroupName -VirtualNetworkGatewayName $gateway.Name -ProcessorArchitecture Amd64
It was giving me an output of:
"https://mdsbrketwprodsn1prod.blob.core.windows.net/cmakexe/xxx~xxx/amd64/xxxx~xxxx&sp=r&fileExtension=.exe"
For some reason (that Microsoft could explain) why it kept adding in " to the beginning and end of the variable.
I find it odd that it lets the script work with " and allows the WebApps to join to the VPN.
Any why here is the fix which basicly removes the " from the begining and end of $packageUri :
$packageUri = $packageUri.ToString();
$packageUri = $packageUri.Substring(1, $packageUri.Length-2);
So hope that helps someone else out there who is banging there head agaist the same problem.
Here is the complete function if any one is intrested:
function AddExistingVnet{
param(
[string] $subscriptionId,
[string] $resourceGroupName,
[string] $webAppName
)
$Vnet = Get-AzureRmVirtualNetwork | Where-Object {$_.ResourceGroupName -like "*Static*"}
IF($Vnet.Name.count -gt 1) {write-host 'Two or networks have been returned. Unable to continue ' return}
$gatewaySubnet = $vnet.Subnets | Where-Object { $_.Name -eq "GatewaySubnet" }
$vnetName = $vnet.Name
$uriParts = $gatewaySubnet.IpConfigurations[0].Id.Split('/')
$gatewayResourceGroup = $uriParts[4]
$gatewayName = $uriParts[8]
$gateway = Get-AzureRmVirtualNetworkGateway -ResourceGroupName $vnet.ResourceGroupName -Name $gatewayName
$webApp = Get-AzureRmResource -ResourceName $webAppName -ResourceType "Microsoft.Web/sites" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName
$location = $webApp.Location
Write-Host "Creating App association to VNET"
$propertiesObject = @{
"vnetResourceId" = "/subscriptions/$($subscriptionId)/resourceGroups/$($vnet.ResourceGroupName)/providers/Microsoft.Network/virtualNetworks/$($vnetName)"
}
$virtualNetwork = New-AzureRmResource -Location $location -Properties $PropertiesObject -ResourceName "$($webAppName)/$($vnet.Name)" -ResourceType "Microsoft.Web/sites/virtualNetworkConnections" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName -Force
# Now finish joining by getting the VPN package and giving it to the App
Write-Host "Retrieving VPN Package and supplying to App"
$packageUri = Get-AzureRmVpnClientPackage -ResourceGroupName $vnet.ResourceGroupName -VirtualNetworkGatewayName $gateway.Name -ProcessorArchitecture Amd64
$packageUri = $packageUri.ToString();
$packageUri = $packageUri.Substring(1, $packageUri.Length-2);
# Put the VPN client configuration package onto the App
$PropertiesObject = @{
"vnetName" = $vnet.Name; "vpnPackageUri" = $packageUri.ToString()
}
$date = Get-Date -format "HH:mm tt"
New-AzureRmResource -Location $location -Properties $PropertiesObject -ResourceName "$($webAppName)/$($vnet.Name)/primary" -ResourceType "Microsoft.Web/sites/virtualNetworkConnections/gateways" -ApiVersion 2015-08-01 -ResourceGroupName $resourceGroupName -WarningAction silentlyContinue -Force
}
Enjoy
