Tailscale
Tailscale has proprietary control plane, but the data plane is based on open source WireGuard. It creates a mesh VPN between your devices, making them accessible to each other securely over the internet. There is opensource alternative for control plane Headscale.
It will create virtual network interface tailscale0 on each device. Each device gets its own stable IP address in the 100.x.y.z range. If you enable --ssh you can SSH to other devices using Tailscale IP or hostname (e.g. device-name.tailcale.net).
sudo dnf install tailscale
sudo systemctl up tailscaled --ssh # one time with SSH
sudo systemctl enable tailscaled # on boot
ip addr show tailscale0
tailscale ping <other-device>

Great with combination with Tailscale for secure access over the internet. Even for gaming.
