At that time, I had in mind that running FreeBSD 10 under Hyper-V and in Microsoft Azure, is something that can be done. So, I decided to build a deployment as a Proof of Concept and to write a blog post about this deployment.
This post will provide instructions and all the necessary steps to prepare, upload and run pfSense-2.2.3 in Microsoft Azure.
Please note, that FreeBSD is not currently an endorsed distribution in Microsoft Azure and therefore is not supported.

Latest Stable Version of pfSense Running FreeBSD in Azure User Defined Routes and other Azure Virtual Network enhancements that announced at Microsoft Ignite 2015 Design
Let’s put, what we want to achieve, into context. The deployment’s design is as follows:
Procedure
In order to prepare a pfSense image for Microsoft Azure, we should download the latest x64 image and install it locally, on a server with Windows Server 2012 R2, as a Hyper-V Virtual Machine:
Download the latest x64 pfSense image from Latest Stable Version of pfSense (As of July 2015 the latest version is 2.2.3) Decompress the image file to extract the Installation ISO pfSense-LiveCD-2.2.3-RELEASE-amd64-20150623-1637.iso Attach the ISO file as a DVD Drive to newly created Hyper-V Virtual Machine
Start the installation of pfSense
After successful installation of pfSense, enable SSH

Shutdown The pfSense Virtual Machine Now the pfSense Virtual Machine is ready for running in Microsoft Azure.
Upload the pfSense-2.3.3 VHD to Azure
Using the following PowerShell commands, first we upload the pfSense VHD to Microsoft Azure Storage Account and then we create a custom image:
# Variables Section $DestFile = "https://pfsa.blob.core.windows.net/vhds/pfSense-2.2.3-amd64.vhd" $SourceFile = "C:\Hyper-V\pfSense\Virtual Hard Disks\pfSense-2-2-3.vhd" # VHD Upload Add-AzureVhd -Destination $DestFile -LocalFilePath $SourceFile # Create an Image Add-AzureVMImage -ImageName "pfSense-2.2.3" -MediaLocation $DestFile -OS Linux Note that we are using OS type Linux instead of FreeBSD as it is not currently supported.
Create a Multi-NIC Virtual Machine
The custom image that we created previously, can be used in order to create a pfSense Virtual Machine with two Virtual Network Interfaces (vNIC), in Microsoft Azure. More details about creating a Virtual Machine with Multiple vNICs in Microsoft Azure, you can find in a previous post here:
Create a Virtual Machine with Multiple NICs in Azure IaaS
A pfSense Virtual Machine with two vNICs will be created by running the following PowerShell commands:
$location = "West Europe" $serviceName = "pfsvc" $vnet = "pf-VNET" $subscriptionName = 'My MSDN Subscription' $storageAccount = 'pfsa' $adminUser = "adminuser" $pwd = "*********" $imageName = "pfSense-2.2.3" $MultiVM = New-AzureVMConfig -ImageName $ImageName ` -Name "pfSense-FW01" -InstanceSize ExtraLarge | Add-AzureProvisioningConfig -Linux -LinuxUser $adminUser ` -Password $pwd | Set-AzureSubnet -SubnetNames "Front-End" | Set-AzureStaticVNetIP -IPAddress "172.16.1.10" | Add-AzureNetworkInterfaceConfig -Name "LAN NIC" ` -SubnetName "LAN-Subnet" -StaticVNetIPAddress 172.16.2.10 New-AzureVM -ServiceName $serviceName ` -Location $location ` -VNetName $vnet ` -VMs $MultiVM
Setup User Defined Routes
With user defined routes, we have complete control over the traffic flow in our virtual network. Virtual network by default provides system routes for traffic flow between virtual machines. Now, we can customize the routing table by defining routes and that is allowing us to direct traffic through pfSense Virtual Machine that we have just created. Routes can be defined inside a routing table and applied to subnets. Every VM within a subnet automatically inherits the routes from the routing table.
The following PowerShell commands, allowing us to:
Create the routing tables Create routes in the routing tables Apply routing tables to subnets Enable IP Forwarding on pfSense’s vNICs # # Variables Section # $Location="West Europe" $VNetName="pf-VNET" $FrontendName="FE-Subnet" $LANName="LAN-Subnet" $ServiceName = "pfsvc" $VM = Get-AzureVM -Name "pfSense-FW01" -ServiceName $serviceName # Set the route table of the Frontend network: # $FrontRT = New-AzureRouteTable -Name $FrontendName ` -Location $Location -Label "FE-RT" Set-AzureRoute -RouteTable $FrontRT -RouteName "DMZ-Route" ` -AddressPrefix "172.16.2.0/24" -NextHopType "VirtualAppliance" ` -NextHopIpAddress "172.16.1.10" Set-AzureSubnetRouteTable -VirtualNetworkName $VNetName ` -SubnetName $FrontendName -RouteTableName $FrontendName # Set the route table of the LAN network: # $LANRT = New-AzureRouteTable -Name $LANName ` -Location $Location -Label "LAN-RT" Set-AzureRoute -RouteTable $LANRT -RouteName "FE-Route" ` -AddressPrefix 172.16.1.0/24 -NextHopType VirtualAppliance ` -NextHopIpAddress 172.16.2.10 Set-AzureRoute -RouteTable $LANRT -RouteName default -AddressPrefix 0.0.0.0/0 ` -NextHopType VirtualAppliance -NextHopIpAddress 172.16.2.10 Set-AzureSubnetRouteTable -VirtualNetworkName $VNetName -SubnetName $LANName ` -RouteTableName $LANName # Enable IP Forwarding on the main NIC and secondary NICs: # Set-AzureIPForwarding -ServiceName $ServiceName -VM $VM -Enable Set-AzureIPForwarding -ServiceName $ServiceName -VM $VM ` -NetworkInterfaceName "LAN NIC" -Enable The pfSense Virtual Machines must be able to receive incoming traffic that is not addressed to itself and this is the reason to enable IP forwarding.
