Since you already have wireguard you don't need any proxies, just set up wireguard to route through the VPS and you should be good to go.
Or you could install a proxy server on the VPS and enter those settings into qBittorrent, if you don't want to use wireguard as a default route.
By "set up wireguard to route through the VPS" you mean having wireguard forward a port from the VPS to a port on the homeserver at its wireguard IP address?
qBittorrent will still need to publish the right IP address to peers though, right? So I will need to configure the proxy VPS's IP address in qBittorrent...
Also that means binding a port on the qBittorrent container directly to the homeserver localhost. I've managed to keep the app containers isolated so far and it'd be nice to keep that, but if proxying the traffic is too annoying I guess I can just say fuck it and go with it.
Yes, he means that.
No. For most things qBittorrent does public IP detection. For the rest your VPS will be doing NAT between the WG interface and the public internet. This means your qBittorrent client sends outgoing packets with the source address of your WG private IP and then the VPS will change those to it's public IP address.
The thing you must be careful about is that you need to restrict qBittorrent to only send and receive traffic on the WG interface, otherwise it will be using both. You can do it in the settings, but the safest way is to do it at the container setup or systemd service level and completely hide any interface that isn't the WG one from it.
Wow thank you, this is the most useful reply I've received so far!
This means I don't need to mess around with QBT's "proxy" settings? I was pretty confused since the only options available are SOCKS/SOCKS5 and HTTP, but I'm guessing that's a different kind of proxy than what I need...
No, you don't. In short, trackers will look at the source address of the incoming connection on their side, that means you VPS IP because you're doing NAT on the VPS.
Just make sure qBittorrent is restricted to the WG interface and nothing else.
Fantastic, thank you
