Oh. I got lost! Could I try to describe it again?
My HW node is staj-dev:
auto eth0
iface eth0 inet static
address 195.113.233.4
netmask 255.255.255.0
network 195.113.233.0
broadcast 195.113.233.255
gateway 195.113.233.1
dns-nameservers 195.113.144.233 195.113.144.194
dns-search cesnet.cz
iface eth0 inet6 static
post-up /sbin/sysctl -w "net.ipv6.conf.eth0.autoconf=0"
address 2001:718:1:e::23:3004
netmask 64
My VE node, has this config (ip6v2-test):
auto eth0
iface eth0 inet static
address 195.113.233.12
netmask 255.255.255.0
network 195.113.233.0
broadcast 195.113.233.255
gateway 195.113.233.4
dns-nameservers 195.113.144.233 195.113.144.194
dns-search cesnet.cz
eth0 inet6 static
iface eth0 inet6 static
address 2001:718:1:e::23:3012
netmask 64
After executing:
brctl addbr vzbr0
brctl addif vzbr0 veth012.0
ifconfig vzbr0 0
echo 1 > /proc/sys/net/ipv4/conf/vzbr0/forwarding
echo 1 > /proc/sys/net/ipv4/conf/vzbr0/proxy_arp
echo 1 > /proc/sys/net/ipv4/conf/eth0/forwarding
echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
ip route add 195.113.233.12 dev vzbr0
ip route add 2001:718:1:e::23:3012 dev vzbr0
**MARK**
VE starts to be reachable from Internet on IPv4. What should I do next?
echo 1 > /proc/sys/net/ipv6/conf/eth0/forwarding
somehow broke IPv6 for HW node.
echo 1 > /proc/sys/net/ipv6/conf/vzbr0/forwarding
cause no problem.
Well - returning to point marked as **MARK**.

VE is missing default GW, I expect it to show there somehow automaticaly
like in HW node... maybe this is one of my bugs.
When I try to ping my HW node, for that I've routes there I get:
[EMAIL PROTECTED]:/# ping6 2001:718:1:e::23:3004

Any thoughts, please?
