Synology rt6600ax for M-Net

[nettanourne]

Hello everyone!
I recently bought an RT6600AX (SRM 1.3.1) router and I'm trying to configure it to connect to the network of an M-Net provider in Germany.
I have connected the WAN port of my router to the LAN port of GPON Terminal Huawei EG8012H5.
To set up the connection, the ISP provides the data:
PPP-User - username
PPP-Password - password
VLAN-ID Data - 40
Protocol - IPv6 DS-Lite
AFTR Address - aftr.prod.m-online.net

In the router settings I specified:
WAN port tagged VLAN 40;
Primary interface: connection type is set as DS-Lite, AFTR address is aftr.prod.m-online.net;
IPv6 settings: PPPoE, username&password, as specified from m-net personal cabinet.
The connection shows as "limited", no internet access.
ISP support replied as follows: "According to the remote diagnosis, the M-net areas for which we are responsible are usable. We have also noticed that dial-up processes occur again and again, but the connection is then always disconnected again after a relatively short time. Apparently not by us. It is therefore reasonable to assume that your own hardware is incorrectly configured."

What I'm doing wrong? How to set it up correctly?

Hello, I'm not familiar with the Synology router, and therefore I can not help in detail for specific settings on this device. But did you have the chance to check with another device to verify that the connection to your ISP in general will be established?

Hast du den Huawei Router von dem ISP bekommen?

Unfortunately, I just moved into this apartment. I don't have any other equipment.

Sorry for the English, my Deutsch is not good enough, I just started learning it.

Yes, the GPON terminal is installed by the provider.

Hallo, ist der Thread noch aktiv? Ich habe EXAKT das gleiche Problem, nur dass ich noch nicht versucht habe, M-net zu kontaktieren.
