I understand the point, but there are a couple of reasons why I'm holding back on this.
- It wouldn't be any easier to set up than it is to set up OpenVPN and peter_sm has two OpenVPN plugins to make it as easy as possible.
- I don't consider myself a security expert. Even OpenVPN (which is made by people definitely more knowledgeable than me in these matters) has security advisories as recent as Sep 12th. Which leads me to the last reason I'd like to bring up and it's a matter of liability.
- Let's say this gets done and users can access their server over the internet, but then someone exploits a bug/flaw in the plugin (which would be required to make this work), a server is compromised and maybe there's data loss. I really don't want to be involved in such a scenario.
To be honest, security is not an easy matter
Personally I use pushbullet for push notifications towards my smartphone, that way if anything bad happens pushbullet notifies me, I then log in to the system using vpn... Works fine..
