A Management Gateway VPN enables easy connectivity from on-premises environment to your SDDC for functionality like Enhanced Linked Mode. Similarly, you can also configure a Compute Gateway VPN for workload mobility. This process is optional and is not required for standalone / non-hybrid environments.
Either IPSec or L2TP VPN tunnels can be configured. Within this guide, we'll step you through the IPSec configuration.
Within the SDDC, click the ‘Network & Security’ tab
Beneath the ‘Network’ section, expand ‘VPN’, click ‘Policy Based’
Once the VPN configuration has been set up on both the local on-premises endpoint and also with the VMC SDDC console, the status icon should change to green with the word "up" next to it. Clicking on the (i) icon can provide more information including any troubleshooting help you may require.
