If there are any issues with the connection this will list them out for you. You can select the gateway on which you’d like to run diagnostics, select a storage account where it will store the sampled data, and let it run. Similarly if you look at the overview page of the site-to-site connection we created on the VPN Gateway on Azure you can see the tunnel status and connection statistics.įor troubleshooting purposes, there is a “VPN Troubleshoot” functionality that’s a part of Azure Network Watcher that’s built into the view of the VPN Gateway. Once that tunnel comes up you can see the connection statistics on the IPSec Status page. Now that we’ve created both the Phase 1 and Phase 2 configurations we can “apply changes” to add those changes to the running configuration.Īfter the settings have saved the tunnel will take a minute to come up, you may take this time to spin up a quick VM in your Azure virtual network to use for testing connectivity. If you wanted to automatically ping a host in Azure to bring up/keep up the tunnel you can configure that here as well. For the Encryption Algorithms required, please see the cryptographic requirements documentation noted above. If we wanted to be exact this would be the 10.2.0.0/16 address space that we configured in our virtual network. I’m designating 10.0.0.0/8 to the VPN assuming that I may expand my Azure environment at some later point. Next let’s create a Phase 2 configuration for the IPSec VPN.
I recommend reviewing the documentation on cryptographic requirements and Azure VPN gateways though for reference. I’m going to be connecting to some other resources with this setting so I am using both AES 128 and 256 with relative SHA 256 hashes and both DH groups 2 and 14. I will want to select the Authentication Method of Mutual PSK and enter the PSK we setup on the Connection on the VPN Gateway in the “Pre-Shared Key” field. Open the IPSec VPN settings page and let’s create a Phase 1 configuration. Once that’s done we’ll go grab the public IP of the VPN Gateway from the overview page so we can go setup the PFSense side of the VPN.Īlright, now let’s go setup an IPSec VPN in PFSense. You’ll want to enter the public IP of the PFSense appliance on-premises and whatever address space you’d like to add to the route table of the virtual network so it knows to route those addresses across the VPN through the gateway. You’ll need to also create a local network gateway which is an Azure resource that represents the information about the on-premises VPN appliance and IP ranges.
Once it’s done we’ll go in and create a “connection”, which we’ll designate as “site-to-site IPSec”, then set the PSK that will be used here and on the on-premises appliance. The VPN Gateway takes about 20-30 minutes to deploy so go ahead and go stretch and grab a cup of coffee.
I’m going to create a new public IP address to be associated with the VPN Gateway, and won’t be using active-active or BGP for this lab so I’ll leave those disabled. You’ll notice that it also selects the special GatewaySubnet that was created for the VPN Gateway. I’m going to be using a route-based VPN, so I’ll use that VPN type and choose the virtual network that we just created. Now let’s go create a Virtual Network Gateway to act as our PaaS VPN appliance. In this particular setup I’m using 10.2.0.0/16 as my virtual network address space and have designated two subnets for a later project.Īfter the virtual network is configured, we’ll need to create a “Gateway Subnet” which is a specific prerequisite to deploying a VPN Gateway into the virtual network.Īlright, the network and subnets are all setup in Azure. I’m going to choose the “West US” region for now since that’s where i’ll be building my resources after this is configured. A virtual network is a regional construct, meaning that it cannot span multiple regions. The first thing we need to do in Azure is setup a virtual network (or vnet). It’s actually pretty easy! Let’s jump into it.
Now, how do we setup a Site-to-Site VPN with our infrastructure hosted in Azure with PFSense. The Netgate Appliances work very well and I’ve worked with plenty of home networks, as well as small and medium businesses that have used them as their cost-effective Router/Firewall/VPN appliance combination. If you’re like me, you like to have a little bit more control over your network (home or business) than is available with the ISP-provided router – enter PFSense.
