A VPN gateway resource enables you to create a secure connection between their on-premises data center and Azure. A VPN gateway resource can be configured in three different ways:
- Point to Site – you can securely access your Azure resources hosted in a VNET by using a VPN client from any computer.
- Multi-site connection – you can securely connect from your on-premises data centers to resources running in a VNET.
- VNET to VNET – you can securely connect across Azure VNETS within the same region, or across regions to build workloads with geo-redundancy.
Key properties of a VPN gateway include:
- Gateway type - dynamically routed or a static routed gateway.
- VPN Client Address Pool Prefix – IP addresses to be assigned to clients connecting in a point to site configuration.
