Connecting to FTTH provider (m-net Munich) with hAP ac2

Hi there!

I purchased a hAP ac2 to replace my under-performing Fritz!Box router supplied by my provider m-net, only to find out that is not a trivial task. while I’m spending my nights reading and playing around, I figured it couldn’t hurt to shout out for help in case there are other m-net or other German ISP customers here that decided to drop their Fritz!Box, or anyone else who can supply some tips…

The details supplied by my supplier are:

PPP-User: *@mdsl.mnet-online.de
Password: **
IP Protocol: IPv6 DualStack
VLAN-ID Data: 40
AFTR Address: aftr.prod.m-online.net

Edit: Since posting this I found a post on my ISPs forum about configuring the connection on OpenWRT: https://www.dropbox.com/s/t5t0un10qdtj9l8/2021-05-09%20Use%20OpenWRT%20router%20with%20m-net%20FTTH.pdf?dl=0 (If required, I can copy specific parts here as text, I just don’t want to spam before it’s necessary)

Can anyone help with understanding how to apply the relevant parts of this configuration on RouterOS?

Any help is greatly appreciated!
Thanks!

Did you find any solution?
