Julien LutranandClaude Opus 5 a7f1ac691e doc: FTTH migration — gateway is now 192.168.0.1

The Archer C7 at .2 is gone; the FTTH box at .1 is the gateway. Every
static holdout (nas host, nuc host, privoxy, transmission-bt) pointed at
the dead .2 and had no internet — the reported symptom was privoxy.

Also record two things the migration broke that were not obvious:

- DHCP reservations did not carry over. blocky held .254 by reservation
  on the C7; a lease renew on the FTTH box moved it and took LAN DNS
  down. It is static now. jellyfin-* are still DHCP on stale leases.
- The FTTH box advertises native IPv6. transmission-bt's tunnel is
  AllowedIPs = 0.0.0.0/0, so v6 egressed around the kill switch on the
  home address. IPv6 is now disabled in that container.

Homelab: nuc

Incus host on the LAN — on-demand: since 2026-08-30 it only needs to run when watching Jellyfin or using the Spotify Connect kiosk. Everything always-on (blocky/DNS, privoxy, transmission-bt) moved to nas, which is why nuc can now be powered off.

⚠️ Powering nuc off has backup consequences — its 03:30 replication to nas only runs while it is up. See nas-install.md §9.

Debian 13, Intel Alder Lake-N (iGPU i915, shared by both Jellyfin containers) — bare-metal reinstall: nuc-install.md
Instances are bridged onto the LAN (192.168.0.0/24)
Storage: ZFS pool data on the SSD (all instance disks). The USB 4 TB and its pool left nuc on 2026-08-30 — the enclosure's JMicron bridge was suspending the pool (usb4t-dropouts.md); the disk now sits on direct SATA in nas as pool tank.
Media library: /srv/media is now an NFSv4 mount from nas (192.168.0.4:/media, read-only). jellyfin-server stays here for the iGPU and reads it with shift=false (jellyfin-server.md).
Backups: nuc and nas cross-replicate — nuc pushes all its instances to nas:nucbackup at 03:30, nas pushes its own to nuc:nasbackup at 04:00, so neither host's instances depend on that host surviving (nas/nas-install.md §9). The ks4 pull leg moved to nas as well (ks2/nas-seed.md), so nuc no longer runs a WireGuard tunnel.
⚠️ Never reboot nuc with the display powered on — the i915 probe dies and takes every container with it (including LAN DNS). Symptoms and fix: jellyfin-client.md

Instances

Name	IP	Doc	Features
jellyfin-server	192.168.0.5	✅	unprivileged, autostart; iGPU render node (`gpu` device, render gid) for QSV/VAAPI transcoding; `/srv/media` disk device (NFS from nas, `shift=false`, read-only); proxy device → host :8096
jellyfin-client	192.168.0.6	✅	privileged, autostart; full iGPU (`gpu` device, gid 44) → HDMI kiosk (cage + Jellyfin Media Player); custom `raw.lxc` (bind `/dev/snd`, `/dev/input`, host `/run/udev`); Pioneer USB audio as ALSA default; FR keymap; go-librespot Spotify Connect ("Pioneer A-70")
homeassistant	(stopped)	—	virtual machine, 50 GiB root disk on pool `data`

Moved to nas on 2026-08-30: transmission-bt (next to the media dataset it writes to), plus blocky and privoxy so LAN DNS and the proxy survive nuc being shut down.
