2.1.2.2 VPN Services
The benefit of a VPN connection is that it is typically very quick to deploy over the Internet, allowing the provider to offer a connection in to their data centers immediately, without waiting for third-party network services companies to provision circuits. VPN services can also be used in conjunction with a direct network connection where required.
With VMware technologies, there are a number of different VPN services the provider can offer to their customers. The following table highlights the service offering examples.

Service Description
SSL VPN-Plus
With SSL VPN-Plus, remote users can connect securely to private networks behind a VMware NSX® Edge™ gateway. Remote users can access servers and applications in private networks.
IPSec VPN
NSX Edge supports site-to-site IPSec VPN between an NSX Edge instance and remote sites.
NSX Edge supports certificate authentication, preshared key mode, IP unicast traffic, and no dynamic routing protocol between the NSX Edge instance and remote VPN routers. Behind each remote VPN router, you can configure multiple subnets to connect to the internal network behind an NSX Edge through IPSec tunnels. These subnets and the internal network behind a NSX Edge must have address ranges that do not overlap.
L2VPN
L2VPN allows you to configure a tunnel between two sites. Virtual machines remain on the same subnet in spite of being moved between these sites, which enables you to extend your data center. An NSX Edge at one site can provide all services to virtual machines on the other site.
To create the L2VPN tunnel, you configure an L2VPN server and L2VPN client.
