golang-based SPR is open-source and can run on RPi: https://github.com/spr-networks/super https://github.com/spr-networks/super > An unspoofable device identity is established with a MAC address and Per-Device Passphrase for WiFi (or a VPN Public Key for Remote Devices). From there, each device gets its own /30 subnet to exist on. Hardening and strict firewall rules block network spoofing and impersonation, and routing rules redefine connectivity between devices and to the internet.
