I have a network currently set up as per the image below.
We use Regus's shared Internet and I've create a sub network for our office by using DHCP and NAT on the airport extreme router. Now the Airport Extreme complains there is Double NAT - but it still appears to work fine. I manually set the DNS servers on each client's network adapter and everything works.
What I am trying to do is set it up so the DHCP from the router auto assigns the DNS servers to the client machines without me having to manually enter them for each client. The problem is when I set the DNS servers on the router to 192.168.1.2 and 192.168.1.1 - this doesn't work and web pages don't load. I am a bit stuck here and manually entering the DNS servers will prove to be a longer process. How can I get the DNS servers to auto assign?
I've been advised that it's better to use the Windows server as a DHCP server, but unfortunately if I want to use the router with NAT, DHCP is forced. Is it better for me to have the Windows Server as the router with NAT and have the Airport as just a bridge?
