Azure VPN Gateway

  • A secured hybrid cloud architecture.
  • It is composed of gateway subnet, tunnel, and on-premises gateway.
  • Protocols: Internet Protocol Security (IPsec) and Internet Key Exchange (IKE)
  • VPN gateway connections: VNet-to-VNet, Site-to-Site, and Point-to-Site
  • Create a secure connection from your on-premises network to an Azure virtual network with a site-to-site VPN.
  • VNet-to-VNet connection automatically routes to the updated address space, if you updated the address space on the other VNet.
  • If you need to establish a connection to your virtual network from a remote location, you can use a point-to-site (P2S) VPN.
  • You can also have one VPN gateway with more than one on-premises network using a Multi-Site connection.
