Yes, layer 4. Nginx as a stream proxy pointing to home directly. No vpn. The only purpose is to hide my IP address. I then configure my firewalls to listen explicitly for the IP addresses of the L4 proxies.

My cloud provider when down last weekend for like 14 hours so I decided to configure another L4 in the US-west datacenter. So now I have us-east and us-west. I then also decided to add another L7 proxy and use the L4s to distribute connections across the two at home.
