Reusable cnx.router.* module for the Topton 1U boxes replacing OPNsense:
PPPoE WAN (optionally VLAN-tagged, AIS: 10, secret credentials incl.
username), VLAN-filtering bridge, nftables NAT/firewall with MSS clamp,
Kea DHCP with per-VLAN lease time, Blocky DNS, DHCPv6-PD, CrowdSec with
the ZeroTier mesh whitelisted, optional Omada controller, ZFS disk.
Fleet baseline rides along: admins sops group is now derived for every
machine in clan.nix (secrets encrypt to it from the first vars generate)
and time sync is chrony everywhere instead of systemd-timesyncd.
Grafana dashboard (auto-provisioned from the dashboards dir) tracks
borgbackup job health, time since last run, and per-job systemd state
from the node_exporter systemd collector on the client. New docs page
covers the ns1 -> control topology, secrets flow, and restore commands.
Docs live in docs/ (DNS, ZeroTier mesh, monitoring), built at Nix-build time and
served as static files over the ZeroTier mesh on control:8080. Commit-to-edit:
change the markdown and redeploy to publish.
