IPv6 Delegated Prefix doesn't stay set
Just as others have encountered after the upgrade to 7.6.3, the required field IPV6 Delegated prefix keeps getting unset. When I click on the error pessage about a broken IPv6 tunnel and click Edit, it highlights the remote IPv4 address, which is set according to the settings specified by tunnelbroker.net. Changing only the IPv6 delegated prefix field and clicking save then update doesn't prompt a reboot. I have to change some of the other fields for the reboot to take effect. My AirPort Extreme is circa 2007 and worked with the 7.6.1 firmware.
