Well, that's what I thought also, but after running the setup on a Linux laptop I noticed that no RAs are actually received. Being a little bit surprise myself I confirmed my observation from a colleague of mine... It's of course a different situation if I setup an IPv6-over-IPvX tunnel over the connection in which case I indeed receive RAs.

Then again, maybe there is just something wrong with my setup.
