OpenVPN use case
Apologies if this is bit of a noob question.
I already use a VPN (ProtonVPN) on my desktop, laptop and phones. If I understand correctly, deploying a Cloudron OpenVPN instance will not offer much additional for device-->outside world.
But I also want to connect securely and easily between computers in different offices. Currently for this I use Splashtop (paid commercial service) which does the job, but doesn't handle wake on lan very well. (I'm attributing that to Splashtop but maybe it's a local issue.)
Will deploying a Cloudron OpenVPN allow me to connect between devices more easily (whether from countryA to countryB, or just from OfficeFloor3 to OfficeFloor1) ? And allow me to cease my Splashtop paid subscription.
Does OpenVPN support wake-on-lan type functionality ? Or that's a function of the device OS ?
BTW, all devices MAC and some Linux (ubuntu). No Windows.
My typical use cases for OpenVPN on Cloudron are:
- static IP (needed for restricted networks)
- VPN from inside public Wifi infrastructure
- Because of a German IP address, public German TV for my friends from Denmark
(And yes: Your use case for a VPN connection between two networks works too.)
To clarify my tests: I was able to "see" another VPN client from a remote location from my location through OpenVPN. If this is also true for complete networks, we have to ask around or try it by our own
The LAN usecase should work really well, yeah, but I would be surprised if you could make wake-on-lan work : for it to work there has to be a device physically on the same network to send a magic-packet for the ethernet card to interpret and trigger wake up.
There are some ways to do wake-on-lan relays stuff, I believe, but you would still have to have a computer awake on the network on which you want to wake another.
Wake-on-LAN is a hardware feature enabled in BIOS.
The sleep state of the CPU has to be integrated with the network card which listens for the wake packets.
So while a particular software may not be able to send a WoL packet, one can set up something that port-knocks on something that does. (Highly unusual)
@mehdi Thank you. Shame about wake-on-lan being local network only. I guess I can set up a wake/sleep schedule eg 8am-8pm so there is at least there is a known window. Or I can arrange for one device to never sleep and connect to that to wake others. Some playing around needed.
