Tailscale does sound pretty cool, and could be an option. It sounds super easy to setup which I like. I have Comcast as my service provider, so I’d have to see what they offer DNS and Static IP addresses.

I have not looked at what all my fileshare options are but doing a bit of digging it sounds like maybe I should look at Samba and see if that would work. They don’t mention mobile device support, but it is free open source software, which I love. I wonder if having a Samba service just for local network file sharing is a security issue. I would assume it is not, but I could be wrong. I’m willing to bet I’d need to be cautious with the configuration of Samba.
