You might try ZeroTier. You’ll each need a tiny client app, but its super easy to install and setup, and extremely secure. Free to use with up to 25 devices.
Can confirm, very easy to setup clients. And since its not a VPN but a VLAN, you wont run into problems connecting between different clients.
This is pretty much open-source Hamachi.
For non tech savy people, is ZeroTier easier to config than Tailscale? I tried Tailscale and everyone needs a account before start playing, which can be a fraction.
Im not sure how difficult it is to setup a Tailscale client, honestly.
The Zerotier setup is just installing and joining a network by an id. The Windows version has a bit of a GUI, where you have to right-click on a status bar icon, click Join network, paste in the id and join. The Linux version of the client has a cli, which is imho even better, as you can just send them a whole command to copy into the terminal.
I admin a Zerotier network for a bunch of kids that wanna play Minecraft, and they havent had many problems setting up.
There is a bunch of information on self-hosting the whole system, but Ive honestly never tried any of that. It was just nice that this was “just the open-source LogMeIn Hamachi with a superior implementation of everything”.
