Thanks for pointing that out, I didnt know that about the fritzbox. Pretty
cool. ;)

I made the trace, but its fairly large: even compressed with bzip2 it's
still around 2MB, probably too large to add as an attachment to this list ?
So I applied a filter of the ipv6 source or destination of my ip (ipv6.addr
== 2001:980:ed37:1:a00:27ff:fe78:8baa
) and attached that to this message.

Anyway, I also uploaded the complete tracefile here :
as : fritzbox.ipv6.pcap.bz2
