IPv6
,proxy_ndp may need to be enabled
In my tests, the container had to be restarted before it would respond to ICMP6 echo requests.
In other tests on 2.6.32-042stab044.11 kernel, container failed to receive Neighbor Solicitation requests and replies, so I had to enable proxy_ndp:
<pre>
# sysctl -w net.ipv6.conf.all.proxy_ndp=1
</pre>
(and later add appropriate line to /etc/sysctl.conf).
