Configuring NSX SSL VPN-Plus

Spas_KaloferovBy Spas Kaloferov

One of the worst things you can do is to buy a great product like VMware NSX Manager and not use its vast number of functionalities. If you are one of those people and want to “do better” then this article is for you. Will take a look how to configure SSL VPN-Plus functionality in VMware NSX. With SSL VPN-Plus, remote users can connect securely to private networks behind a NSX Edge gateway. By doing so remote users can access servers and applications in the private networks.

Consider a software development company that has made design decision and is planning to extend it’s existing network infrastructure and allow remote users access to some segments of it’s internal network. To accomplish this the company will be utilizing the already existing VMware NSX Manager network infrastructure platform to create a Virtual Private Network (VPN).

The company has identified the following requirements for their VPN implementation:

  • The VPN solution should utilize SSL certificate for communication encryption and be used with standard Web browser.
  • The VPN solution should use Windows Active Directory (AD) as identity source to authenticate users.
  • Only users within a given AD organizational unit (OU) should be granted access to the VPN.
  • Users should be utilizing User Principal Names (UPN’s) to authenticate to the VPN.
  • Only users who have accounts with specific characteristics, like those having an Employee ID associated with their account, should be able to authenticate to the VPN.

If you have followed one of my previous articles Managing VMware NSX Edge and Manager Certificates, you have already made the first step towards configuring SSL VPN-Plus.

Configuring SSL VPN-Plus is a straightforward process, but fine tuning it’s configuration to meet your needs might sometimes be a bit tricky. Especially when configuring Active Directory for authentication. We will look into a couple of examples how to use the Login Attribute Name and Search Filter parameters fine grain and filter the users who should be granted VPN access.
