Hi bugs@,
it turns out it was just a concidence that I've only noticed the
broken IPv6 setup after the upgrade. The real cause of the problem
was a half-set up iked which installed
flow esp out from ::/0 to ::/0 type deny
as a default IPSEC flow. This persisted after a reboot because I had
already enabled iked to be started by default. Martin requesting
configuration files then caused me to cut down the set up so I could
provide a minimal configuration that yields the problem and of
course after disabling iked and rebooting, everything worked fine.
The bottom line is: nothing to see here but a stupid operator.
Thanks and sorry for wasting your time :)
