Hello, I have a Raspberry Pi 4 Compute Module as Router and a DrayTek Vigor 167 as modem, my ISP has DS-Lite, the Setup works fine. (I used the Wiki example for 1&1) But the WAN4 and WAN6_4 interfaces are not in the Firewall Zone WAN, is this a reasen to worry? I have added WAN4 to Zone WAN but LuCI doesn´t allow me to add WAN6_4.
So is these even needed?
