OK, so the first thing is to get yourself set up with a VPN company. I have only ever used PIA (Private Internet Access) and it has never, ever let me down in over 12 months of regular use. It costs about £30 for a year or £5 for a month, they do not track usage (at all) and you can use it on up to 5 different devices (so you're Android "side" of the box can be covered too by downloading the app from the google play store).
Having said that, other VPN providers are available. ipVanish are recommended by Droidbox but I've never used them so I can't comment. A complete list of VPN providers that work with LibreElec using the method I'm going to describe is:
- Private Internet Access (PIA)
- ipVanish
- VyprVPN
- Invisible Browsing VPN
- NordVPN
- tigerVPN
- Hide My Ass!
- PureVPN
- LiquidVPN
- AirVPN
- CyberGhost
- Perfect Privacy
- TorGuard
- HideIPVPN
- LimeVPN
- BTGuard VPN
- ExpressVPN
- SaferVPN
- Celo VPN.ht
- TotalVPN
- WiTopia
- proXPN
- VPN.ht
- Windscribe (Pro accounts)
- VPN Unlimited
- VPN.ac
- VPNSecure
Just because they are supported though doesn't mean they are any good. I'd use a well known one if I were you, choice of VPN provider is important for a number of reasons.
So when you have signed up to a VPN, you will be provided with a username and password. Keep a note of that.
Go to this website:
https://github.com/Zomboided/service.vpn.manager/wiki/01.-Installation
This is where you can get the repo that will give you the VPNManager addon that you will need.
Full instructions are available on that site but I will summarise here.
Download the Repository (I download the repo rather than the standalone addon so you get automatic updates) to a mac/pc.
Copy that over to LibreElec (I copy it in to the downloads folder but its up to you). I use Samba to copy across to LibreElec If you don't know how to do that, check out
https://wiki.libreelec.tv/index.php?title=Accessing_LibreELEC#tab=Samba_2FSMB
If you have any specific challenges with that just shout back.
Next, go to your addon explorer in LibreElec and install the repo from the zip you have just put on to LibreElec (In your file list click the Home Folder button then the "Downloads" folder or wherever you copied it over to). That will give you the Zomboided repo. It's the same process as installing any addon/repo from a Zip file, just that it is in your home folder rather than a website you need to define in File Manager.
Next, click install from repository and install the VPNManager addon from the Zomboided repo you have just installed. Give it a minute, it will get there.
Go to Program Addons > VPN Manager and open it up. If it doesn't come up with a "Wizard" option at this point, click Settings when the addon has opened and it should give you the option to set up using a wizard. Choose the wizard and then choose your VPN Provider from the list that comes up.
Put in your username and password for your VPN. Let it do it's thing.
In the settings of VPN Manager go to VPN Connections. This is where you choose which server you want to connect to by default (when you open LibreElec). Choose a server (the closer to you the better for speed) and click ok. Then you can choose secondary, third etc. servers if you wish but it's not essential.
That's it. Now, every time you switch on LibreElec after a couple of seconds it will say "Connecting to VPN" or similar at the top of the screen then give you a message saying it has connected. You're then good to go. There is no need to disconnect before switching off either, just switch off as normal.
There are a LOAD of settings in VPN Manager that you can tweak if you wish (so mine is set to Southampton server but if I open IETVNow which needs you to be based in Ireland, VPN Manager automatically connects me to Ireland without me doing anything) but my advice is to take it slow and get to know it. If you don't know EXACTLY what an option is going to do, leave it alone.
There's loads of info and good instructions on the Zomboided GitHub site (above) so give that a read too. If you have ANY questions on it though I will do my best to answer, just shout.
Good luck!
