Virtual network gateway resources are deployed to a specific subnet named GatewaySubnet. The gateway subnet is part of the virtual network IP address range that you specify when you configure your virtual network.
If you don't have a subnet named GatewaySubnet, when you create your VPN gateway, it fails. We recommend that you create a gateway subnet that uses a /27 (or larger). For example, /27 or /26. For more information about the gateway subnet, see VPN Gateway settings - Gateway Subnet.
