I need help setting proton VPN on the WireGuard client, which will then be used on qTorrent on my media server. However, I’m not sure how the process works. I’m using an unraid server. Any help would be appreciated.
Have you read through the documentation? I don’t use ProtonVPN but this appears to be what you are looking for. https://protonvpn.com/support/wireguard-configurations/
They even have a section on how to bind the VPN to qbittorent. https://protonvpn.com/support/bittorrent-vpn/
Follow this Guide also.
