I'm also trying to curl a specific tracker from within the container, but when I docker exec into the VPN container and run the curl it fails, citing either "Couldn't connect to server" or "Timeout was reached". Curling the same sites from outside container succeeds normally. Additionally, some other sites can be curled from within the VPN container with no issues at all (like example.com). I need the request to go through the VPN container so that the tracker can see what IP my requests will be coming from.
