I have already set up all of that. My setup is similar to the one in this blogpost and it’s already working for various apps that only use HTTP. What I’m trying to do is to also route BitTorrent traffic (TCP/UDP) over the same setup without opening up entirely new paths.
I indeed have a domain name pointing to the VPS IP, with Caddy managing TLS. Other apps are exposed this way, and I will do the same for the qBittorrent WebUI as well. I like having Caddy as a single gateway where I can apply security configs and monitor all traffic, I was hoping I would be able to pass torrent traffic through it as well but everybody seems very much against it.
I already have wireguard setup as you describe so I guess I’ll just give up on passing torrent traffic through the proxies and just open a localhost port on the qBittorrent container…
