Spectra SME Firewall — downloads

Two ways to install: the turnkey ISO (boots and self-installs to disk — no OS needed) or the .deb for your own minimal Debian 13 host. Then run fwctl init on the console. Always verify the SHA-256 before installing.

Install
1. sudo apt-get install -y ./spectra-smefirewall-1.3.0.deb — apt pulls the dependencies. (Upgrades an older perimeter-firewall install in place.)
2. sudo fwctl set-nics --wan-mac <WAN> --lan-mac <LAN>
3. sudo fwctl init — set LAN/WAN/admin on the console (no web UI needed for first boot).
4. Browse to https://<LAN_IP>/ and, under Settings → Licence, point at your Spectra endpoint and activate.
