[ipv6hackers] Autoassign IPv6 address to the interface SENDIN OUT the RA?

your problem can not be solved like this :-)
your network adapter does send the RA packet to the network to an
all-node multicast address, so when the packet is echoed on the network,
your network adapter will ignore it and not pass it on to your kernel.
your kernel never sees sees packets itself sends as incoming traffic.
Two solutions: manual configuration, or let a 2nd server also sending RA
so your first server is picking them up ...
The second solution I'd call an ugly hack, so it fits the purpose of
this mailing list ;-)
