That’s a really good mention. I’m pretty sure firejail is usig linux namespaces too. It has a flag called --net
which accepts interfaces, so you could pass an existing VPN connection to it before it launches the torrent application. Probably a much cleaner way of doing it than YAML config files like I was suggesting.
This is the best answer. Just ask the author for a copy. They’ll often time have no problem sending it to you for free.
