Hello all, I don't seem to find any question(/answer) on if it is possible to route a private IPv4 VPN over (SixXS) tunneled IPv6 points. The reason why I would want to do it this way, is that the IPv6 (SixXS) address doesn't change (even if I've seen before in some RFC that this won't necessarily remain like that, as allocated IPv6 addresses can be reclaimed), there where IPv4 addresses change over time. Working this way with fixed IPv6 addresses doesn't then necessitate to use dyndns entries necessary in a IPv4 setup. I seem to have read somewhere, in the past, that this kind of IPv6 setup isn't possible when working with tunneled IPv6, but I can't find it back, even after having browsed the SixXS Setup forum logs up to 2009. Before continuing on my intention, I thought I'd better ask here if that setup makes sense and/or is possible at all.
