One option is what I currently use, a docker image of Qbittorrent with support for OpenVPN: https://hub.docker.com/r/markusmcnugen/qbittorrentvpn
If you can get OpenVPN config files from CyberGhost then it should be straightforward to set up.
Yep it's much easier to use a container with basically everything already setup. I use the one from binhex: https://hub.docker.com/r/binhex/arch-qbittorrentvpn/
Seems to be basically the same thing as the one you linked but also supports wireguard.
You can use a container that includes a vpn client like others mentioned OR you can have a container that uses the network of another container!
The basic idea is that you have a single openvpn/wireguard container and then you route all the other containers to use that network, see this stackoverflow post for more info.
The only downside of this solution is that you have to open the ports that you need in the vpn container.
I use gluetun to provide VPN access for specific containers like qBittorrent-Nox, Sonarr etc. There is a wiki for how to connect containers on docker and setup CyberGhost.
Kind of overkill. Just use iptables and route by uid
What I do on mine is rent a cheap VPS with unlimited bandwidth, I run OpenVPN server on that VPS using Nyr's openvpn-install script and then on my local seedbox server I connect to my OpenVPN server. I have qbittorrent-nox listening on the tun0 interface, and then on my OpenVPN server VPS I have an iptables prerouting rule to route traffic from the inbound torrent port to my local seedbox server, essentially port-forwarding over the VPN using the iptables prerouting DNAT rule. I also only seed on private trackers, since I don't use public trackers.
It's a very nice setup, I'd recommend it. I might do a full write-up some time about it.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
