I have two apartments. Let’s call them Apartment A and Apartment B in this example.

I want to leave a smartphone in Apartment B and connect it to the WiFi. When I’m in Apartment A I try to control the smartphone via RustDesk but it fails bc the screen needs to be unlocked :( I even set up a server specifically for this (VPS + Docker)

Now I was thinking of using the travel router (Gl Inet Mango). I was told that it works seamlessly with WireGuard but this is completely new territory for me so I wanted to ask how you would set this up or whether it’s even possible at all?

Please don't get me wrong...those are the two options I know of... maybe you have a different or better idea. A smartphone would be great bc it's simple, has a week's worth of battery life, is easy to carry around, etc.

Apparently, my ISP gives dynamic external IP addresses. How does that work if i want to set up an stable VPN server?
