My ISP, like many today, doesn't allow incoming connections, so if I try to host server software on my home PC, then anyone (even myself) trying to connect to that server software via my public IP address is not able to establish a connection. This becomes a problem because hosting online games is impossible. I do have a VPS Linux box rented; is there any VPN software I could install on it that I could connect to from my home PC, and then anyone connecting to a specific port on that VPS will just have the traffic tunneled to my home PC, allowing me to host games that way? If so, what software do I need (on both my PC and on the VPS), and how do I configure it?
