You have an Azure subscription. If you don't have an Azure subscription, create a free account.
-
You have a virtual network to which you want to connect.
- Verify that none of the subnets of your on-premises networks overlap with the virtual networks that you want to connect to.
- To create a virtual network in the Azure portal, see the Quickstart article.
-
Your virtual network must not have any existing virtual network gateways.
- If your virtual network already has gateways (VPN or ExpressRoute), you must remove all of the gateways before proceeding.
- This configuration requires that virtual networks connect to the Virtual WAN hub gateway only.
-
Decide the IP address range that you want to use for your virtual hub private address space. This information is used when configuring your virtual hub. A virtual hub is a virtual network that is created and used by Virtual WAN. It's the core of your Virtual WAN network in a region. The address space range must conform the certain rules:
- The address range that you specify for the hub can't overlap with any of the existing virtual networks that you connect to.
- The address range can't overlap with the on-premises address ranges that you connect to.
- If you're unfamiliar with the IP address ranges located in your on-premises network configuration, coordinate with someone who can provide those details for you.
