qbittorrent, linux cli, nordvpn, openvpn, split tunnel!

I FINALLY got around to properly split tunneling. You know... to get my linux isos

Nothing here is specific to nordvpn. Just an example service.

• install openvpn
• Create /etc/openvpn/nordvpn.auth with permissions of root:root 440 (I think these permissions work lol, TODO: verify it works)

ServiceUsernameHere
ServicePasswordHere

• Download openvpn config file from nordvpn and put into /etc/openvpn/
• Rename to .ovpn to .conf. ex: /etc/openvpn/pt1234.nordvpn.udp.conf
• edit to not be full tunnel:
  • add route-nopull
  • add auth-nocache
  • change auth-user-pass nordvpn.auth
• Start service with sudo systemctl start [email protected] (dont add .conf)
  • ex: sudo systemctl start [email protected]
  • note: sudo service start will not work! service doesn't take params like the @
• check if it working with sudo journalctl -xeu [email protected]
• Make it stay on reboot with sudo systemctl enable [email protected]

Note:

• sudo systemctl restart [email protected] DOES NOT WORK! You must do STOP and then START.
• I believe the openvpn service will just control all .conf files it finds in the directory. Which means that just placing a .conf there will create/run that tunnel. Rename unused tunnels with a .off or something.

actual todo: look into doing wireguard instead. apparently you can use the nordvpn official program and extract the config file from nordlynx

changelog: 2023-07-10 added split tunnel lines, auth file permissions, openvpn service note, small formatting
