Hello,
i have a IPv6 problem since i upgraded to 6.3. I cannot reach other
hosts anymore over IPv6. Over IPv4 everything works fine. I have read
the part with RFC 7217 in the faq/upgrade63.html but as far as I
understand it I am not affected by that.

> PING google.com (2a00:1450:4001:814::200e): 56 data bytes

The server is a normal 6.3 installation without any modifications. The
only thing I changed is /etc/ntpd.conf, the rest is as default as shipped.
Here is the config:

The IPv6 gateway itself is fully reachable.
