It is disabled:

staj-dev:~# for f in /proc/sys/net/ipv6/conf/*/forwarding; do echo $f;
cat $f; done
/proc/sys/net/ipv6/conf/all/forwarding
0
/proc/sys/net/ipv6/conf/default/forwarding
0
/proc/sys/net/ipv6/conf/eth0/forwarding
0
/proc/sys/net/ipv6/conf/lo/forwarding
0
/proc/sys/net/ipv6/conf/venet0/forwarding
0

Problem is that when I do:

echo "1" > /proc/sys/net/ipv6/conf/all/forwarding

HW node stops responding on IPv6 ping, reason probably is that setting
that removes default GW:

staj-dev:~# route -6
Kernel IPv6 routing table
Destination Next Hop
Flags Metric Ref Use Iface
::1/128 ::
U 0 13 1 lo
2001:718:1:e::/128 ::

fe80::1/128 ::
U 0 0 1 lo
fe80::213:72ff:fe1b:b97/128 ::
U 0 8 1 lo
fe80::/64 ::
U 256 0 0 eth0
fe80::/64 ::
U 256 0 0 venet0
ff02::1/128 ff02::1
UC 0 229 0 eth0
ff00::/8 ::
U 256 0 0 eth0
ff00::/8 ::
U 256 0 0 venet0

When I set GW manualy it start work and it works also for VE. GREAT!

Well and now. Why setting forwarding=1 removes GW? Is there any way how
to add it there automaticaly without my attention? I'm afraid that GW IP
fe80::215:faff:fe87:3100 is somehow related to router MAC and that it
will change when router become replaced. Any sugestion on this?

Thanks a lot!
