Hello forum!
I must admit that regarding networking I know as much as a pig knows of physics, therefore I turn to you with a simple question. As a little background, I've been using OpenVPN to access my home network and tunnel my smartphone network traffic thru my house when not at home. I've successfully used it during my vacations and it worked perfectly to both protect my network traffic and to gain access to all my stuff on my server from wherever I am.
After the vacations I returned with a ton of pictures and my grandma (who lives in the other side of the world) would love to see them. I have no interest in uploading 5 Gb of pictures to Google, Facebook, etc. for my grandma to have access to it. Therefore, since the experiment with OpenVPN was successful I thought about a similar solution to grant her with read-only access to the folder where the pictures are. I thought about different options and was looking for pros and cons and would like to know your recommendation:
1. OpenVPN would be the most straightforward solution, but configuring a VPN is out of the question for my 86-year-old grandma
2. FTP: It seems to me that it is the simplest solution, but AFAIK it is not that safe. I would create a user with restricted read-rights to the folder where the pictures are. That way she can see the pictures via web browser.
3. You tell me.
Thanks in advance for the help
