With wifi + Starlink + cellular as uplinks, the onboard GbE earns its keep as a wired LAN port instead of the metric-150 ethernet WAN: eth0 leaves netplan/NM (added to van-ap-unmanaged.conf) and joins br0 via networkd (23-van-lan-eth0.network), so wired clients get 10.42.0.x DHCP/DNS and NAT exactly like Wi-Fi clients. The eth WAN is gone from van-failover's config. Cutover notes: delete the old netplan-eth0 / stray eth0 NM profiles, then nmcli general reload + networkctl reload/reconfigure eth0. NEVER cable this port (or the USB LAN dongle) back into an upstream LAN — dnsmasq on br0 would serve rogue DHCP there; STP stays off, so don't cable both wired LAN ports to the same switch either.
