IPv6 problem after 6.3 upgrade

Tue, 03 Apr 2018 05:57:13 -0700 

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. 


# ping6 google.com
PING google.com (2a00:1450:4001:814::200e): 56 data bytes
^C
--- google.com ping statistics ---
12 packets transmitted, 0 packets received, 100.0% packet loss



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:


# cat /etc/hostname.vio0
