I have a Windows Server 2k8 with 2 NIC Cards installed (1 for WAN, 1 for LAN), I have installed AD, DNS, DHCP on that server.

IP Config for NIC Card for WAN:

IP: X.X.X.4 (public IP from my ISP)
Subnet: X.X.X.X
Gateway: X.X.X.1 (public IP from my ISP)
DNS 1: X.X.X.X (ISPs DNS Server)
DNS 2: X.X.X.X (ISPs DNS Server)


IP config for NIC card for my LAN:

IP: 192.168.1.1
Sbnt: 255.255.255.0
DG: 192.168.1.1
DNS: 127.0.0.1

Now I want my AD users / DHCP clients can use Internet through this server. AD is working, DHCP is also working. But whenever i want to install NAT in this server its shows some error.
My server is connected to the Internet itself. Please help me so that I can install NAT service in this same server and my users through this server can use internet also as they are using Active Directory Services.

Well there's a couple of things that's wrong here, first you should never have your pdc connected straight to the internet without some type of firewall appliance between it and the internet.
