If you make 2.1 you could add some info on the port forwarding because there are massive differences on it between providers. Like PIA gives you a single random port that changes each time you reconnect, while AirVPN gives you 5 static ports you can configure yourself.

AirVPN lets you open 5 ports and allow p2p. Works with their app and openvpn/wireguard. I’ve been paying for it couple years now and I’m pretty happy with it

This looks nice, thank you

What should I use if I just want dumb file storage that is accesible from any device (linux/windows/android) remotely? I’m already self hosting a media server if that matters

They will still provide new version of the bootable usb stick for linux users
