Setting up a VPN between Azure and on-prem SonicWall

I needed to setup a VPN between an on-prem SonicWall and Azure, but found the documentation on Sonicwall.com here a bit dated.

Here’s some updated documentation for how to configure the tunnel to supplement the link above.

Let’s setup the Azure side first:

1. Setup a Virtual Network.  If you don’t already have a virtual network setup, you’ll need to start there. I recommend setting up at least a /16 for the virtual network, then setup /24 subnets within the virtual network as needed.
2. Setup a Virtual Network Gateway.  Next, we’ll setup a virtual network gateway attached to the Virtual Network created in Step 1.  This step will also require the creation of a Virtual Network Gateway IP.
3. Create a Local Network Gateway.  This step defines the public IP address of your SonicWall and corresponding LAN subnet(s).
4. Within the Local Network Gateway, create a Connection.

Now to the on the on-prem side:

1. Create a tunnel IPSec VPN
2. You’ll need to create an Address Object, @AzureNetwork, Zone=VPN, Type=Network. Use the network and subnet of your private IP scheme in Azure. (not pictured).
3. Create a route
4. At this point, your VPN should be up!
