So on my host I run Mullvad VPN all the time due to living in one of the X eyes countries and being over-paranoid, but when I torrent I do almost no uploading due to Mullvad blocking port forwarding. I had the bright idea to create a VM then attach it to my network in a way to completely bypass my host (also running Linux) connection and in-turn bypass Mullvad, I'd then connect this VM to my own Wireguard server that I rent overseas and configure port forwarding on that. I think I'm almost there however I seem to have hit a roadblock that I think the only workaround is attaching a second ethernet cable to my host, in order to get another interface so that the VM doesn't steal my host's connection.

Doing the dual ethernet setup isn't impossible, but it is extra cables and dongles that I'd rather do without, so I was wondering if I could create a second IP address on my host and pass that into the VM to use? I'm using qemu and virt manager for my virtual machines, Artix on my host and probably Linux Mint on my torrent VM.

Again I have no idea if this is possible or not, I simply don't know enough about networking yet to know for certain. I feel like it is but I wanted to ask some people who know what they're talking about :D.
