Hi Martin
In fact, the 6rd solution was only implemented for residential customers, but was never thought to be used for SME products. It only worked by chance, as the Border Relays were reachable also from SME IP-ranges. We recently had to scale up the border relays, due to increased traffic (6rd works extremely well and is highly performant, it is about to be enabled for all residential customers by default).
Nice to hear the IPv6 adoption is about to make another big step forward.
At the same time the Border Relays were placed at a different location in our network. This means that they are no longer reachable from the IP ranges of the SME customers. Hence the interruption, I'm sorry it cannot be made to work easily.
That explains why the SME support didn't have a clue what I was talking about.
But if it's indeed working as good as you say, why not keep it active for the SME IP range in the meantime?
Again, IPv6 was never officially supported for SME products. An official PPPoE-based solution is being worked on, so I hope you activate a few tunnels in the meantime and we won't lose you as a customer.
Don't worry about me, I'll figure something out. There are still good tunnel brokers out there. Just make sure the CPE / router / firewall vendors and the SC partners get the technical and organizational details in time to be prepared for it.
Thanks for the clarification anyway.
Regards
Jean-Pierre
