Yeah, maybe. Sunrise actually has a free choice of router, so the setup described should work. However, there are many reports that the Sunrise connection with a third party router did not work. So: if it works, then everything is tiptop. If it doesn't, then you'll have to deal with extremely poor (in my opinion) support from Sunrise. But the configuration itself works.

Hello,
I have just finished my configuration on a Sunrise 1G/1G fibre connection: Everything works but I still have some small problems with the VOIP.
For those who are interested here is the link to the configuration:
