VPS + VPN is the cheapest option I believe for the services. It doesn’t have to be “elaborate”.

You can port-forward public VPS ports to your private addresses/ports. If you don’t want to use iptables you can use firewalld.

The only “but” will be latency. For gaming it won’t perform as you may need.
