Yes, this is a left over from the v8.100b and it is still broken.
I have been trying to workout why my access to IPv6 google had suddenly failed, then it dawned on me, I had changed the lease time from infinity to see if this had been fixed.
No, it hasn't been fixed and I now cannot get an IPv6 address assigned.
What steps have I taken
1/. changed the settings back to infinity
2/. restarted the PC
3/. restored a backup from before the change date
4/. restarted the PC
5/. stopped and restarted the DHCP servers
After all that no IPv6.
Next step, re-install from ISO. Not happy.
