Virtual private networks (VPNs) allow you to securely connect a remote device or a remote site to your corporate infrastructure. NSX Edge supports three types of VPN connectivity. SSL VPN-Plus allows remote users to access corporate applications securely. IP-SEC VPN offers site-to-site connectivity and L2 VPN allows you to extend your data center by allowing virtual networks to span across data centers securely.
SSL VPN-Plus allows remote users to securely access applications and servers in a private network. There are two modes in which SSL VPN-Plus can be configured: network access mode and web access mode.
In the network access mode, a remote user can access the internal private network securely. This is done by virtue of a VPN client that the remote user downloads and installs on their operating system. In web access mode, the remote user is able to access the private networks without any VPN client software.
