To setup the router with my ISP ONT, I have to spoof the mac adress and chager the vendor class when requesting IP ( i already did this), but I have also to pot WAN port to VLAN 100.
I figure out how to do it, I added interface eth1.100 to wan, than I go to the normal GUI and on ethetnet 1 on DHCP SETUP a put VLAN 100.
I don't really understand but it work, why we have Ethernet 1 and ethernet 2 on the GUI? I thought that's for LAN configuration but it seem refer to WAN PORT (at lest for ethernet 1)
also I enebled IPV6 on GUI, than go to ludi and configred wan 6 to ger IPV
