Why do you have two interfaces defined over 'eth0.2'?

shouldn't the dhcp server be like this?

You have both a DHCP client and a PPPoE client on the same interface... that cannot be right. Can you post details about your configuration and the tests you are performing, please?

Are you able to post details about your configuration and the tests you are performing?

I still do not understand why you have both a DHCP and a PPPoE client on the same interface... Unless you have some special requirements, I think you should go back to the default configuration, then change the WAN interface from DHCP client to PPPoE client, and not change anything else.
