Using NSX Edge, you can create a L2 VPN that can stretch multiple logical networks, whether VLAN or VXLAN, across geographical sites. With L2 VPN, a VM can remain on the same subnet when moved between sites and their IP addresses do not have to change. To configure a L2 VPN, you configure a L2 VPN server (destination Edge) and an L2 VPN client (source Edge). Then you enable L2 VPN services on both. But before we can create the L2 VPN, we must create a trunk port on our NSX edge. Read Full Article
With SSL VPN-Plus, you can connect to private networks behind a NSX edge gateway. A user can then access applications and servers on the private network. Since this is a SSL VPN, a user can access the private networks by use of a web browser or a client that is installed on the local machine. Below is a diagram taken from the NSX Admin Guide of the clients connect to the private network and also the support operating systems for the SSL VPN client:
NSX edge supports site to site IPSec VPN to remote sites. You can configure multiple internal networks to connect to through the VPN tunnel. Subnets and internal networks behind the NSX edge must not have overlapping addresses. The size of the edge device determines the number of tunnels that are supported. The number of tunnels needed can be found out by using a simple equation of : “local subnets x peer subnets = number of tunnels needed”. Below is a chart taken from the NSX Administrator’s Guide outlining the number of IPSec tunnels that a edge device can handle depending on the size and also the supported algorithms.
