OpenVPN Port Passthrough?

I am attempting to route server traffic from a windows machine to my Ubuntu 20.04 server using OpenVPN (My goal is to mask my IP address from my home IP but still allow people to connect to the server)

I have OpenVPN setup and I can connect and I’m sure this is probably actually simple but I don’t know the linux knowledge needed to create such a passthrough.
I want to be able to host multiple servers with different IP’s and as long as they have an exemption on my Windows firewall they will port and be open on the Linux server to connect to publicly if that makes since.
If anyone could help me out I am open to ideas and or a guide. I have very beginner knowledge of Linux but I am pretty computer literate so hopefully with someone’s help we can make this monstrosity exist.

Thanks!
