As reported elsewhere, IPv6 tunneling seems to be broken in the 7.6.3 update.
After updating the Airport Extreme (4th gen) tells me that the IPv6 connection is broken and wireless clients are not assigned IPv6 addresses. I tried several different IPv6 tunnels (tunnelbroker, etc) and none worked in 7.6.3. Reverting to 7.6.1 immediately solved the problem.
Glad to help!
IPv6 tunnel broker no work!!! help me !!!!!!
Ok. You need to provide us some more information. What kind of tunnel do you have. What are your settings that don't appear to work.
John
John, I, like you, have a SixXS tunnel (with a routed /48) that stopped working after I upgraded to 7.6.3.
The new firmware insists on specifying a delegated prefix, which is fine... I carved a /64 off of my /48 and set it as the delegated prefix in Airport Utility. However, the change does not take. In fact, if I open the IPv6 config again, the delegated prefix field is empty.
Airport Utility seems to be doing some sort of validation of the delegated prefix field that is rejecting everything I put in there. I've had to downgrade to 7.6.1 to get my tunnel working.
MIke,
Do you want to debug this or are you happy with the roll-back? I suspect that you have a configuration issue.
John
I'd like to debug it, if possible. The problem, as far as I can tell, is in Airport Utility, not the firmware. Airport Utility will not accept anything I specify as the delegated prefix. I've slightly scrambled my information so as to avoid giving my actual IP:
IPv6 WAN Address: 2001:1939:85:271::2
IPv6 Default Route: 2001:1939:85:271::1
Remove IPv4 Address: 209.197.5.66
IPv6 Delegated Prefix: 2001:1939:3df:ada::/64
IPv6 LAN Address: 2001:1939:3df:ada::1
When I click "Save", it appears to have been successful. But when I open "Internet Options" back up, the IPv6 Delegated Prefix field is blank.
Mike,
One thing I see:
LAN Address should look like this;
2001:3948:0011:410d::
Prefix is:
2001:3948:0011:410d::/64
John
Even if I specify it like that, leaving in all the leading zeroes, it still rejects it silently.
Below example still does not work:
Prefix: 2001:1939:3df:ada::/64
LAN Address: 2001:1939:3df:ada::
I feel like it is rejecting it due to something else, perhaps because the third "octet" of the /48 does not match the IPv6 WAN address, but that is SixXS's doing and it's never been a problem before...
Test that theory. Put 2001:1939:85:ada::/64 in prefix and 2001:1939:85:ada:: just to see if it will save that.
John
No dice. I've posted to ipv6-dev list (https://lists.apple.com/mailman/listinfo/ipv6-dev) to see if they have any ideas.
Mike,
Let me send you my IPV6 configuration values for IPV6 prefix and LAN address to see if my values will save. Email me at john.c.vestal@mailzone.com and we will see if we can get any values to save.
John
Here is a good read on setting up your tunnel for an AirPort Extreme. It was posted using earlier firmware but maybe it'll help.
Unfortunately, the ars technica fix does not seem to work for 1st Gen. Time Capsules.
I've tried quite a few combinations using the instructions for the ars technica mentioned by @Speleding and I cannot get IPv6 tunneling to work on my 1st Gen. Time Capsule.
I too get the silent rejection of the setting which aren't saved as has been previously described.
Reverting back to 7.6.1 yet again..
Do you want to debug this or are you ok with the downgrade? I am willing to help you debug.
John
IPv6 tunneling broken after 7.6.3 update
