Are there any VPN’s that work on PostmarketOS ? I would be using on the Pinephone CE; Pinebook Pro and Rock Pro 64. I usually use Proton VPN or Mullvad but i’m not overly picky.
While I have not personally used any of them, I guess as long as they support standard wireguard or openvpn, they should work fine.
Mullvad supports Wireguard and works for me - I recommend setting up NetworkManger with a Wireguard config which is a bit involved, but afterwards it’s well integrated into Phosh.
Note that you don’t actually need to use whatever app the VPN provider has. They all support common protocols, often WireGuard and/or OpenVPN, and you can just configure them using the DE tools.
Do it manually?
All desktop clients should work but might not be the most responsive
