Q: This is all great but for me the "IPv6 Delegated Prefix" field never sticks. After the reboot to apply the settings, it is empty again. I have tried the 6.2 Airport Utility on OS X 10.8.2 and the iOS Airport Utility. Any ideas?

Hi All,

 

   I had a working IPv6 tunnel with my Airport Express to tunnelbroker.net using the 7.6.1 firmware.  After updating to 7.6.3, I have tried many things to get it to work and the only one that works is downgrading from 7.6.3 back to 7.6.1.  After seeing this new technical note, it appears that the root of my issue is that I can not get the "IPv6 Delegated Prefix" field to stick - it is always empty after the reboot to apply the settings.

 

   Any ideas?

 

     Thanks,

    Hi Craig,

    Just to confirm: You're not alone. My tunnel that was previously working does not work anymore since I upgraded my TC.

    Whatever I type in the newly added field "IPv6 Delegated Prefix", this doesn't get stored on my TC.

    May be I misunderstood something in http://support.apple.com/kb/HT5656?

    Thanks

    I'm in the same boat with a 3rd Gen AEBS.  Only thing I haven't tried is a complete reset and reconfiguration from nothing, which I may wind up doing this afternoon just to rule it out.  The best irony of all of this is that tunnelbroker.net is under my responsibility, and I can't validate the new settings paradigm.  At least getting back to 7.6.1 is easy enough and everything works fine there.

     

    IPv6 Delegated prefix doesn't get saved when using the format from their example, then a 6to4 address shows up as the local address on the main Internet page, and no RAs are received once the AEBS comes back from a reload.  Something's a little off on this release.
