PPPOE config on Fritzbox and Sophos XG

Username/Password is the provider credentials. Basically the XG can use PPPoE to login to the ISP network. 

You need to configure the router to be a modem bridge.

Then you need to configure XG as you did but with the provider credentials, which basically should be in some kind of paper or you should have in a online portal. Sometimes you have to register only to get those credentials send to you. 

Thank you for your reply Toni

i did found the credentials for my Online Account for the Sunrise Portal - i tried it with them but same..

Still no public IP on this port   and no internet connection from the other ports, i tried the config of my post and this one:

FYI: The connection from other ports couldnt be the problem because i did give the WAN port a fixe ip from fritzbox which allows the internet connection also from the other ports with the any to any rule.

how you think can i troubleshoot in this case?

Check if the Provider use VLAN or not (VDSL). And check why the PPPOE interface is unplugged. 

i have receive firstly the false login data this is why it couldnt connect.

it now says "connecting"

does it take some time till it finds the connection?

its still the same config as my first post.

Thank you for your help Toni

Hi Chicho,

Assuming Fritzbox is currently configured in bridge mode.

Check PPPoE events for interface Port2 under Log viewer > System, apply filter with 'PPPoE'

You can also check packet flow in CLI by following the below steps.

==> Login to SSH > 4. Device Console

console> tcpdump interface Port2 -e

Please share session output & log viewer snapshot here or in PM.

Dear Yash

Thank you in advance, i apreciate it. This is the UI output:

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.
