I run a VPN client on my Pi. I’d like to access my NAS through the Internet, and from what I gather the safest way is to run a VPN server and connect to that. I already connect to a VPN service on my Pi, would that interfer with me running a VPN server at the same time? I’ve never run a VPN server before. I can open ports on my VPN server that I connect to with my Pi. Could I open the required port there, and then connect to my VPN server through that tunnel?
edit: I have a second Pi elsewhere, if I install openVPN on that, can I connect to my first Pi with openVPN and access the NAS on my first Pi on the second Pi?
