In this section, IPsec VPN tunnels are created between the Azure VPN gateway and the on-premises VPN device. The examples use Cisco Cloud Service Router (CSR1000) VPN devices. The following diagram shows the IPsec VPN tunnels established between on-premises VPN device 1, and the Azure VPN gateway instance pair.
IPSec Virtual Tunnel Interface - Cisco Systems IP security (IPsec) virtual tunnel interfaces (VTIs) provide a routable interface type for terminating IPsec tunnels and an easy way to define protection between sites to form an overlay network. IPsec VTIs simplify configuration of IPsec for protection of remote links, support multicast, and simplify network management and load balancing. What is IPSec VPN ?

You use a Site-to-Site VPN connection to connect your remote network to a VPC. Each Site-to-Site VPN connection has two tunnels, with each tunnel using a unique virtual private gateway public IP address. It is important to configure both tunnels for redundancy.
Configuring the VPN Tunnel¶ First, log into the pfSense firewall for the local network and click VPN > IPsec. IPsec tunnels have two components: A Phase 1 area that defines the remote peer and how the tunnel is authenticated, and one or more Phase 2 entries that define how traffic is carried across the tunnel. Cookbook | FortiGate / FortiOS 6.0.0 | Fortinet In this example, you allow remote users to access the corporate network using an IPsec VPN that they connect to using FortiClient. The remote user Internet traffic is also routed through the FortiGate (split tunneling will not be enabled). Optionally, you can create a user that uses two factor authentication, and an user LDAP user. Site to site IPSec vpn Phase-1 and Phase-2 Troubleshooting
