In general, this is of course 100% based on speculation, but I assume that you can connect to a VPN but you cannot access any resource inside the local network. Just because this is the most basic mistake that beginners usually make. And it’s related to the fact that your pi is not your default gateway. To solve this, you need to enable SNAT on the local Pi interface. There are many guides on the Internet on how to do this.

P.S. Unfortunately, I have a poor telepathy skill, so it would be good to get a little more background. At least an accurate description of the problem. =)

Look:

1. you can buy any VPS server or use free VM in Amazon cloud
2. then connect your home PC to this VPS with VPN tunnel After that you have public IP address (on VPS) linked with you home server.
3. configure VPS for pass through incoming ports to you home server After that you can host anything for anyone in v4 or v6 internet.
