IPv6 tunneling broken after 7.6.3 update

Same here

Debugging sounds fun!

What information will you need to begin?

Thanks,

Jeff G.

Ok. Let's start with the working tunnel in 7.6.1. Please give me the values in your tunnel setup. If you are worried about giving the values in public just switch the position of the numbers or change them. The ipv4 address should be numbers less than 255 the ipv6 you can literally mix the order of what you have but I will need you to be consistent with your changes going forward. So when I k for stuff always make the same changes that you start with, :-)

I've sent the info to your email address that was previously provided. Hope that's OK!

I'll update here with anything that we figure out in order to make it available to everyone.

Apple has posted the same fix athttp://support.apple.com/kb/HT5656 but this does not work for me but it appears to work for others...

Craig,

You don't happen to have a 1st Generation Time Capsule do you? What happens when you do what Apple suggests? Do the values not stick or it still gives the error with the correct values saved in the configuration?

John

The fix documented does not work for my Airport Extreme as the "IPv6 Delegated Prefix" field looses its contents when the airport reboots to apply the new settings. Anyone else seeing this?

I have a 1st gen Gigabit Airport Extreme which I think is about the same generation as the 1st gen Time Capsule. Are you also seeing the "IPv6 Delegated Prefix" field not sticking?

What generation AirPort Extreme? What year? The short answer is others are seeing this. Try re-applying the firmware. Also, does the value stay when you exit and go back in the ipv6 configuration or is it cleared before it gets saved?

John

I don't have first generation. I have helped two other people here with 1st generation that are seeing this behavior.

John

The value does not remain set either immediately after setting or after the restart of the 1st Gen Time Capsule.

I would do a factory reset; however, I have a ton of DHCP settings that I'm not ready to retype at this time :-\

Anyone else have a 1st Gen Time Capsule and have successfully configured IPv6 tunneling after a 7.6.3 update?

Jeff G.

With my 1st Gen Gigabit Airport Extreme, the "IPv6 Delegated Prefix" field sticks until you click "Update" and the airport reboots. After reboot the field is empty...

I have tried reflashing back to 7.6.1 where it works again and then back to 7.6.3 and I have also tried a factory reset in 7.6.3 and reconfiguring everything from scratch but to no avail...

Hmmm... I wonder if I can use the Export Configuration File and Import Configuration File to my advantage.

I'll use TextWrangler to edit the file with the expected IPv6 information and then import it back into the Time Capsule.

What could go wrong? 😝

I've decided to hold off on the above mischief for now and went ahead and submitted feedback to Apple.

I'm fine at 7.6.1 on my 1st Gen. Time Capsule for the time being.

Thanks everyone!

I have a 3rd generaton AirPort Exteme. The 7.6.3 upgrade broke my IPv6 tunnel. I tried to input the "IPv6 Delegated Prefix" and got no errors on save but when went to look at it again the value was blank.

An additional problem: I first tried to edit the "IPv6 Delegated Prefix" from my 10.6.8 laptop and there the "IPv6 Delegated Prefix" option was not in the AirPort Utility app. My 10.8.2 computer did have the "IPv6 Delegated Prefix" option and that is where I was not able to save the "IPv6 Delegated Prefix".

I was hoping for an answer here. Until Apple support addresses this issue, I am back to 7.6.1
