VPN server on Rock pi 4c

Hello everybody. I bought myself a rock pi 4c + penta sata hat, and I would like to make my VPN server out of it, do not tell me which openvpn would be better on it, or is there something better? I purchased rock pi for the first time and have stayed on my server with vpn for now, so I would like to know about future problems in advance. After the work done, I built a penta sata hat on my rock pi4c and installed debian 9 on emmc, everything works without problems so far.

You can just go with pivpn. It’s user-friendly OpenVPN
