Vlan encapsulation to remove tags to connect PPPOE server

Hi,

I have a scenario:
Vlan2(port 1-4),Vlan3(5-8) and Vlan4(9-12) in one L2 24port-switch and carry all Vlans traffic through trunk port(port 24) which is connected in mikrotik router os ether port1. PCs conneted in Vlan2,3 and 4 are PPPOE clients trying to connect a PPPOE server which is connected to mikrotik’s ether port 2.
I tried different conifg to connect server but failed.
Is there anyone who has implemented this scenario to share the details.

Thanks,
Ajmal

What did you already try to connect the VLANs to Ether 2 at layer 2?
