I have a Synology NAS at home. I have installed the VPN Server package and enabled Open VPN. I don't want to use the QuickConnect and I want to minimise the number of port for port forwarding. I understand that there will be at least one port I need to port forward (the OpenVPN server one) I have the following questions.
How do I access my photos on the Synology using the DS Photo app or Moments app from my iPhone? I have installed OpenVPN app on the iPhone along with DS Photo and Moments app.
Do I need to register my NAS with a Domain Name Provider? like buy a unique name on the internet if I want to connect using OpenVPN?
Do i need to buy a new digital certificate for my NAS? Or is it enough to use the default certificate that Synology provides with the NAS?
Will my NAS be exposed on the internet?
Finally, will the communication between my device and the NAS be secure?
