How can I share one Internet connection in an AD-integrated network?
I have a small network with one DNS server and two DCs. I wanted to share an Internet connection and bought a proxy program, which didn't work. So I tried NAT. I know it shouldn't work with a DNS server already in place, but it seems to, although it does cut out intermittently. The only way I could get it to work was to have the NAT server point to itself and the other DNS server as DNS servers and all clients point to the NAT server as a gateway with DHCP enabled. Is this worth pursuing or should I give up and get a proper proxy program like Windows Proxy Server? Or is there any other way of sharing one Internet connection in an Active Directory-integrated network?
I don't know why you say that you can't use DNS with NAT -- it's definitely possible. Unfortunately, I don't completely understand how you've set your network up, so I can't provide any specific guidance. The best I can offer at this point is to suggest using NSLookup and Network Monitor to isolate the problem when it does stop working. Good luck!
