Hello everyone.
This is my first post to the forum. I’ve been a silent reader for some time but now I felt to give something back.
I’m in the middle of a change of my ISP and I’ve had a hard time the last few weeks getting the provided Fritz!Box replaced by RouterOS (A spare one at the moment, but intention was a proof of concept.)
I could not have done this without this forum. A big thank you!
Up to now, I’ve vodafone via cable as my ISP (Germany (NRW)). I have the modem in bridge mode where it’s not capable of IPv6, so I got a public IPv4 and was happy.
My new provider is Deutsche Giganetz (NOT Deutsche Glasfaser), fibre connection who only does DS-Lite. DS is possible, but at extra costs of 3,90€/month.
Deutsche Giganetz seems to be a reseller of PURtel in germany.
The reason why I’m writing to this post is that it’s the newest one I could find and many others were very helpful but I always found stuff like “needs tweaking” or else. Additionally, somewhere else I read that KPN fibre is supposed to be quite similar to Deutsche Giganetz.
Long story short, It’s working for me (99%).
The most trouble I had was getting traffic through the IPIP6 tunnel other than ping or traceroute. It was possible to ping but websites in browser showed timeouts, even if freemail.de turned to web.de in address bar. IPv6 capable websites worked without problems.
Here is my full config

I hope I did the code tags right.
The default config has been pretty much left alone, except for the interfaces.
I’d also appreciate if someone could give me a hint what to tweak and how. Right now I’m happy that it works, even with a registered SIP-client in LAN.
the 1% that is not working right now is, that this config does not survive a reboot. dslite interface comes up too early before pppoe-out1 and IPv6 dhcp-client is fully up. I have to disable and than enable the dslite.
If someone has a hint how to achieve that automatically, I’d be happy.
So hopefully I did the code tags right and this post will help someone.
Thank you!
for advice.
