Then in another thread I was advised to use App vpn for you. 
It was certainly a good idea. This is because you don’t have to create a Vpn-Qube with Fedora every time.
However, I have never used an app VPN yet, and I wanted to use an open VPN or WireGuard VPN that has a successful experience. Also, since I want to create multiple sys-whonix, sys-firewall, sys-net, etc., as well as VpnQube, I thought it would be necessary to install a clean FedoraQube or whonix-gateway.
