I have a homelab outside of russia that has gigabit connection, port forwarding availiable, is always running, and has Linux Mint installed, I want to setup a VPN on it so my friend in Russia can use the internet unrestricted. I also have a domain and DDNS service which refreshes to my IP address constantly. I do not want to pay for a VPS.
I have tried using things like x-ui, 3x-ui, etc but I had to stop halfway through because there was some issues that stopped it from working, mostly because I do not have much knowledge about VPN protocols, website domains, SLL/TLS certificates, etc so I have no clue of what the hell I am doing. I would prefer a simple setup. Kind Regards.
