Hi!

My Cisco router is working fine with Ethernet and IPv6. There is a “little” problem concerning the promotion of IPv6 addresses under WLan. When I’m using WLan the router is not providing any IPv6 addresses, only IPv4. Do you have any clue why the router is not promoting the IPv6 addresses.

btw. I will post the config later on, when I’m at home.

Cheers

I have this problem too.

What are you using for wireless, a controller, autonomous AP, or integrated AP?

If its a controller IPv6 is not natively supported yet.  It will bridge IPv6 if you enable support for it but the client will still have to run a dual stack (IPv4 and IPv6).

It´s an integrated AP!
