VPN support has been hotly requested since the creation of the service. I'm happy to announce that starting today we are able to support the Wireguard implementation of VPNs. I know many of the requests have been specifically for OpenVPN, please bear in mind that Wireguard is simply a technologically superior implementation of a VPN and performs significantly better than OpenVPN servers do (we're all about performance here). Given this, it is unlikely that swizzin will support OpenVPN in the future.
You can get started with Wireguard by issuing the command:
sudo box install wireguard
If you need help configuring a client (Linux/OS X are officially supported, Windows unofficially), check out the KB article here.
As always, as this was just released, there may be a few lingering gremlins in the code. Please open a ticket if you find you're having issues with the package and I'll do my best to get it sorted.
Enjoy!
