IPv6 behind RRAS NAT doesn't ping

[therock]

Hello everyone,

I have a Dualstack modem.
Behind that a 2008R2 server with RRAS and NAT.
Behind the server is my second server (2008R2 DC) which has a static IPv6 adres.

How can I get this to work? i guess that it has something to do with the NAT function within the RRAS, but can't seem to find out where the problem is.

Thank you in advance.

Jonathan

is is possible your firewall is blocking ICMP for IPv6?

Thanks iphonogasm,
There is no firewall. And the software firewall on the windows server has been disabled for testing purpose.
