Windows Server 2008 R2 as gateway - problem

I've set up a Windows Server 2008 R2 to simulate a gateway. The HE tunnel is up and running and accessing IPv6 resources on the internet from the server works perfectly. The server runs dual stack with IPv4 and IPv6.

The server is running a DHCP server distributing IPv4 and IPv6 addresses. The clients get addresses and communication between server and clients is okay on both protocols.

The problem is that the clients can't access any IPv6 resources on the internet. I'm thinking this may be a routing problem? Can anyone assist me on this problem.


Let's see the routing tables and the output of ipconfig /all from a client that doesn't work.

I don't think the DHCPv6 implementation in Server 2008 will provide a gateway address, so you'll need to configure Windows to also do Router Advertisements


The problem was the router advertisements. It's working now.

Thanks for the answer cholzhauer :)


Glad to hear it.

Could you do me a favor and post the commands you used?  You don't have to post your IP ranges (actually, you should use the 2001:db8:/32 documentation prefix)  I'd like to see how you got it to work
