Hello Yerni,

I have found this KB article:

Could you please tell me if it helped?

Regards,

Create a new VLAN interface on the Fortigate Firewall by clicking Network -> Interfaces and then clicking the + icon. Enter a name for the VLAN interface and select the physical interface to which the VLAN will be bound. Also set the VLAN ID.
Configure the PPPOE interface by clicking "Network" -> "Interfaces" and then clicking the "+" icon. Select the VLAN interface you created earlier and select "PPPOE" as the connection type. Enter the required PPPOE authentication details, such as username and password.
Configure the routing by clicking on "Network" -> "Routing". Add a new route by clicking on the "+" icon. Specify the destination network and the gateway. The gateway is the IP address of the router connected to the PPPOE network.
Check your configuration by clicking on "Monitor" -> "IPsec Monitor". Verify that the PPPOE interface is active and that the routing tables are configured correctly.
With these steps, your Fortigate router should be able to access the Internet via PPPOE and use the VLAN to transfer data between different networks.
