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.
