So I decided to roll my own router with an Intel NUC running Debian trixie on a managed switch with a VLAN to the ONT and a PoE wifi mesh as my house is wired Cat5e. Everything working great from an IPv4 perspective - solid as a rock with great WiFi coverage. Problem of course is IPv6. I just get a local link (fe80) address. Does anyone know what my systemd-networkd WAN interface settings should be. This is what I have - it's the latest of many iterations that doesn't work.
