Mullvad is a VPN service with an emphasis on privacy. It supports WireGuard and is easy to set up in Linux.
I prefer to use the CLI as it allows me to map keyboard shortcuts to the commands.
Installation
Debian/Ubuntu:
wget https://mullvad.net/download/app/deb/latest/ -O mullvad-cli.deb
sudo apt install ./mullvad-cli.deb
Arch:
yay -S mullvad-vpn-cli
Configuration
First you must link your Mullvad account using your account number:
mullvad account login
To list relay locations:
mullvad relay list
To chose a relay location:
mullvad relay set location country city hostname
The city and hostname is optional. I have chose Sweden becuase all of the VPN servers are owned by Mullvad.
It is recommended to use WireGuard over OpenVPN as it is faster and more modern.
To verify WireGuard key:
mullvad tunnel wireguard key check
To generate a WireGuard key to replace your current one:
mullvad tunner wireguard key regenerate
To set the tunnel protocol to WireGuard:
mullvad relay set tunnel-protocol wireguard
To reset the tunnel protocol:
mullvad relay set tunnel-protocol any
To set tunnel protocol to OpenVPN:
mullvad relay set tunnel-protocol openvpn
To connect to VPN:
mullvad connect
To disconnect from VPN:
mullvad disconnect
