We have set up IPv6 networking on openvz using bridged veth devices. The IPv6 traffic to and from the VEs works fine.

ip6tables works on the HN and iptables work on the VE. Inside the VE we can set up ip6tables rules without any error messages. They are completely ignored however.

What additional configuration options are necessary for ip6tables to work?

Might be worth doing a ip6tables -I INPUT -j LOG and seeing if packets are actually hitting the filters. If they are, try adding similar lines throughout the filters (particularly after any expected drops) and see what gets logged to syslog. – Andy Smith Nov 30 '11 at 21:45
Make sure the iptables features you require are in the vz.conf file. – awmusic12635 Apr 8 '15 at 2:31

Make sure you are applying the rules to the venet0 interface by explicitly.
