PPPOE config on Fritzbox and Sophos XG

Hi all

I want to configure my Fritzbox 7590 as a modem, i did it like this for havin my Public IP on my Sophos XG, i tried like this:
https://emil.network/netzwerk/fritzbox-als-modem-nutzen/ My fritzbox Config:

But I also tried this one:
https://deer-it.de/fritzbox-7412-modem-bridge-mode-pppoe-passthrough/

My Sophos config looks like this:
the credentials (username & password) are those for the Router, right?

i read that the public ip should be recognized automatically but
i also tried to set the public ip on the field "preferred IP" but still no connections from the other ports of the firewall.

If you dont have a solution may also troubleshooting steps would help to find the solution ;)

thanks in advance!

    As per the log events, XG has sent a discovery request(PADR) packet, but there’s no session confirmation(PADS) packet coming from the PPPoE server.

    PADR: PPPoE Active Discovery Request

    PADS: PPPoE Active Discovery Session-confirmation

    ==> Here is a sample snapshot to understand PPPoE packet flow.
