Creating a "local" VPN Network
Now that I have a point-to-point Wireguard connection between my desktop and my VPS, I want to create a small network of devices that can communicate with each other over the VPN. This will look like a “local” network, but it is actually a virtual network overlaid on the internet and my home network.
With such a network I should be able to, for example, connect to my home desktop from my laptop when I am away from home (without needing to open ports on my home router).
I am aiming to create a spoke-and-hub network where the VPS is the hub and my home devices are the spokes. Something like this:

subgraph home
A[Desktop<br>10.20.10.2]
B[NAS<br>10.20.10.3]
end
subgraph roaming
C[Laptop<br>10.20.10.4]
end
V[Wireguard Server<br>10.20.10.1]
V <---> |tunneled| A
V <---> |tunneled| B
V <---> |tunneled| C
subgraph internet
I[...<br>0.0.0.0/32]
end
internet <---> |untunneled| V
