Hello, FYI: The mentioned problem in the following message of the IPNG-Mailinglist might be interesting and an issue for the IPv6-WG at RIPE... I will not forward the whole thread of the IPNG-Mailing to this list; it has been suggested to take the issue to the IPv6-Forum. I suggest we should spend some time at the upcoming RIPE-Meeting for this issue (even, if we only check whether it is an issue for the IPv6-activities in RIPE-community).

This is obstacles for transition from IPv4 to IPv6. Are there any activities in IETF to recommend ISPs not to filter "IPv6 in IPv4" packets?
