I need IPv4 and IPv6 support in VE.

Host node have IPv4=195.113.233.4, IPv6=2001:718:1:e::23:3004/64. That
is working ok.

VE 233012 is supposed to have IPv4=195.113.233.12,
IPv6=2001:718:1:e::23:3012/64.

Gateway for IPv4 is 195.113.233.1 and for IPv6 it somehow works without
GW. Config from host node:

I've no idea how to draw that. Task is simple: Get IPv6 support inside
VE 233012.


I would prefer venet interface, but that doesn't work. See thread:
http://forum.openvz.org/index.php?t=msg&goto=12809&& amp;srch=IPv6#msg_12809

So I'm trying experiment with veth.

Ok. I will use anything which will make it to work. I tried to restart
staj-dev to get clean environment and typed:

staj-dev:~# brctl addbr vzbr0
staj-dev:~# brctl addif vzbr0 veth012.0
staj-dev:~# echo 1 > /proc/sys/net/ipv4/conf/vzbr0/forwarding
staj-dev:~# echo 1 > /proc/sys/net/ipv4/conf/vzbr0/proxy_arp
staj-dev:~# ip route add 195.113.233.12 dev vzbr0
staj-dev:~# echo 1 > /proc/sys/net/ipv4/conf/eth0/forwarding
staj-dev:~# echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
staj-dev:~# ip route add 2001:718:1:e::23:3012/64 dev vzbr0
staj-dev:~# ip route add 2001:718:1:e::23:3012 dev vzbr0
staj-dev:~# echo 1 > /proc/sys/net/ipv6/conf/eth0/forwarding
staj-dev:~# echo 1 > /proc/sys/net/ipv6/conf/vzbr0/forwarding

IPv4 is working fine. But IPv6 still not. :(

Thank you for your help so far.

Do you have any other suggestions?
