How to connect two IPoE lines

I am trying to use two IPoE lines in one fortigate.

 

The configuration is as follows.
IPoEâ‘ : for Internet
IPoEâ‘¡: for maintenance such as Windows Update

How should we configure it?
I know how to set up only one line.
Should I use VDOM?

It is version 7.4.3.

 

Thank you for any answer
Best regards

The main question is: who is receiving these IPs from IPoE, the FortiGate, or the end client? 
My answer was for the end client machine, which should have 2 physical/virtual mac addresses, and this can be achieved (I think) with 2 different VLANs. If you refer to FortiGate as a client for IPoE, it really needs nothing else. Each port is a separate client and will receive an IP address independent of the other.

There is close to no information on IPoE, but as I see, the DHCP is assigning IP addresses based on the Physical info of the devices. So if the user lands on another VLAN, it may get another IP address assignment (from a different DHCP server configured). Is there any limitation on using VLANs for IPoE? I don't imagine how this can be done with only a single connection from PC to the switch/FortiGate

    Thanks for the answer.

    I did not understand what you said about VLANs.
    If IPoE assigns IP addresses based on physical information, then I should just set up two virtual MAC addresses, right？
