A VLAN is very different from a VPN.
With VLANs, you can separate traffic that goes over the same physical wire.
With a VPN, on the other hand, you can connect devices from anywhere on the planet, as if they were in the same LAN, which bypasses firewalls, NAT and all that crap. Presumably, you want a VPN.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Try tailscale!
If you’d like a GUI, use Trayscale with it.
The Linux version does not provide a GUI on its own, but still makes it super easy to login and manage
A VPN is what you want, not VLANS that is used to segment parts of the local network. not to get your friends in too your local network.
A simple and easy to use solution is wireguard easy.
Yeah, I have an OpenVPN TAP server running for this purpose. (TAP so that broadcast packets work)
If your distro uses NetworkManager (very likely): nm-connection-editor
I'd rather set up a VPN for yourselves. Many routers can act as a VPN. Maybe you and your friends should check your routers if they are capable of doing that. Could be the easiest option.
