1- I have formatted new server and I installed windows server Enterprise 2008 r2 64bit sp1
2- I have two NIC on the server, I called the first NIC: LAN and the second is: WAN.
3- I installed domain controller, DNS, on the server.
4- Server is connected to the internet via NIC I called it WAN and it takes a real IP.
5- The other NIC I called it LAN and it is connected to switch where other PCs are connected too.
6- I need to join 20 PCs to the domain controller, and let them share internet.
7- What are all possible methods that I can do to connect 20 PCs to the internet VIA this server? Please notice that I cannot install forefront TMG 2010 in the same AD/DC server.
Please help? thanks
