IPv6 Native woes

Hi All,

blablabla, skip to the end to get a basic idea of what is wrong.

I recently got a dedicated server @ kimsufi's.
Just to play around with and have some fun with IPv6.

Unfortunate the network setup is a bit odd to say the least.
I have 2 IPv4 Address, each one is assigned to a mac address of a nic in VMware. This is working fine so far.

However there is also an entire /64 IPv6 block that gets send to the same set of interfaces :confused:

So I carved that into 2 subnets, assigned a /80 to astaro's internal interface.
Setup RA and that is now working fine.
I gave one of the WAN facing nics an IP out of the 2nd /80 subnet.

Great! I can now ping for example ipv6.google.com from a VM that is located on the same vSwitch as the internal nic. (GW set to the IP on the nic)

However inbound traffic does not reach the VM. I assume this is because the traffic will arrive at (I assume both) WAN nics, but astaro does not know how to route it.

I tried adding a static route without success.

So basicly I have an entire /64 block, I can assing addresses to the WAN facing nics and they are usable. However I can't assing them to hosts on the internal side
