Hi All I have a question would you please help me? I have windows server 2008 by 2 NIC and I should connect to internet by using VPN connection.I want to configure NAT for sharing this internet on my private network. How can I do that?

You will need to configure it so that the Internet connection is made by a demand-dial interface. You do not need to use the demand-dial option but the connection must be made from RRAS using a demand-dial interface. You can then use that interface as the public interface for NAT in RRAS. http://technet.microsoft.com/en-us/library/dd469686.aspx Bill

Thanks Bill I created demand-dial interface and it is connected but the server is not connect to internet.I don't know why. Would you please tell me what is the problem? Thanks Mohsen

How did you connect before? You have to do exactly the same things except through the demand dial interface. Once you can get an Inernet connection through the dd interface you can share the connection through RRAS.Bill

Thanks Bill I connected to the internet via VPN connection but I don't know what is wrong now. I created demand-dial interface like a VPN connection and it is connected but there is no internet. what can I do? Regards Mohsen

Hi Mohsen, Thanks for posting here. > I created demand-dial interface and it is connected but the server is not connect to internet. Have to make sure the default gateway entry on you internal-facing NIC is empty. Otherwise please post the route table from server here when demand-dial is be connected.

Hi Mohsen, Thanks for explanation. But could you post the router entries that I asked previously here which might probably help us to narrow down this issue more effectually. Thanks.
