As a operations person, this is the wrong way to go. The VPN becomes a single point of failure. Attempts at HA fail in my experience.
Also solutions like stunnel create a separate process that has to be managed. If I have one for redis, and then one for something else it is harder to tell them apart, because both will be named stunnel.
