I've static setup on HW node:
iface eth0 inet6 static
post-up /sbin/sysctl -w "net.ipv6.conf.eth0.autoconf=0"
post-up /sbin/sysctl -w "net.ipv6.conf.all.forwarding=1"
address 2001:718:1:e::23:3254
gateway 2001:718:1:e::1
netmask 64
Traceroute from HW node:

Could you please try traceroute at 2001:718:1:e::23:3254? Path seams to
be different from yours. But I'm not sure if that could indicate
something bad in your IPv6 network setup. I'm not able to reach machines
which are in our own network so it looks like something more
fundamental. For IPv4 I will say that arp is not working but ...
