  • NAT on Server 2008

    I'm trying to clone a Server 2003 to a new machine using Server 2008. The server's job is to connect the internet to an internal network (using two NICs) allowing VPN in and serving as a NAT firewall outbound.

    I have RRAS (with NAT), DHCP & DNS working on the new machine which is also it's own DC.

    VPN inbound works ok, and internet from the console is fine, but I cannot get a client on the internal network to get access to the internet. The client can do DNS for the internal network, but doesn't get any DNS from the internet either.

    Am I missing something? I am running ISA on the old server which acts as a proxy/firewall, but that doesn't run on Server 2008. I don't see where that is necessary just to get the NAT to work.

    ISA is not supported on Windows 2008, therefor you can't use it.
    However, TMG is released and that is the next generation of the ISA firewall.
    checkout http://www.microsoft.com/forefront/t...gateway/en/us/

    So scratch the box, reinstall windows 2008, install TMG and you all good to go configuring TMG server.
    Also ISA or TMG is way stronger in their security then Windows itself.
