Let’s Encrypt

When you want to use the same public IP address for multiple websites, you have to leverage the SNI extension. Server Name Indication (SNI) is an extension to the Transport Layer Security (TLS) protocol which allows a client to indicate which hostname it wants to connect to. This allows a server to present specific certificates on the same IP address and hence allows multiple secure (HTTPS) websites to be served by the same server.

The NSX-T Load Balancer supports SNI Certificates on a single Virtual Server (IP Address) with different Server Pools in the backend. This article explains how to configure SNI-based Load Balancing with 3 different secure HTTPS Websites on a single IP Address with the NSX-T 3.1 Load Balancer.
