Yes this one. It is strange - I saw this report so I figured it was the problems I was experiencing.

I have a working ipv6 network at home (fritzbox, ipv6 tunnels, etc)

The n900 gets an ipv6, which I can ping6 from the lan and which can ping6 to the lan as well, but that's all - it can not ping6 external machines, or wget -6 from them, while they are properly resolved.

ip -6 route shows the proper route - identical to other machines on the lan. /proc/sys/net/ipv6/conf/all/disable_ipv6 is not set

I haven't found similar reports of this problem. I'd like to keep ipv6 but it also causes problem with my google talk account, which works only if I disable ipv6 :-/

Any idea?
