- [wayback campervan AP](wayback-campervan-ap.md) — the whole build: dual-band hostapd (5GHz 80MHz/HE + 2.4GHz ch6 on separate rtw88 dongle/instance) + dnsmasq + nftables NAT, NM owns WAN, multi-WAN failover daemon, Cockpit "Van Router" plugin. Hard-won gotchas (rtw89/rtw88 power-save, USB-hub load hang, reapply→carrier flap, EEE, curl `if!`). Source of truth: ~/vanlink/.
- [ZeroTier managed DNS](zerotier-managed-dns.md) — wrede.pvt resolves over ZT via zerotier-systemd-manager + systemd-networkd (native ZT setDns is a no-op on Linux).
- [wayback fan max = EC latch](wayback-fan-max-ec-latch.md) — fan stuck at max was a latched EC failsafe; fixed by full power-drain reset (warm reboot won't clear it).
- [Home Assistant VM](homeassistant-vm.md) — HAOS runs as libvirt KVM VM `ha_van` bridged onto br0 at 10.42.0.50:8123 (name `homeassistant`; legacy 10.42.0.1:8123 DNAT kept); documented in vanlink repo under ha/. The old NAT+iptables-hook setup rotted on libvirtd restarts.
- [LAN port + asymmetric mgmt access](lan-port-and-asymmetric-mgmt-access.md) — enx00e04c331140 bridged into br0 as a wired LAN port; never SSH to 10.42.0.1 from the upstream LAN (asymmetric path, drops at ~125s) — use wayback.lo/.zt.wrede.pvt.
- [Pi 4 'wan' port](pi-wan-port.md) — full vanlink stack on the Pi (192.168.6.128, branch `wan` of its own clone), live since the hub moved 2026-07-06. Watch: netplan-wpa unit fights NM; bcm2835 watchdog max 15s; HA VM + ZT route still need a plan; cockpit-bridge EMFILE fixed (batched spawns + LimitNOFILE drop-in).
