Lab Problem

Hi

I'm trying to setup a lab at home to test domain controllers and virtualization and I basically need a lab network inside my home network. I currently have a comcast modem. Not a modem/router but just a modem and connected to that is my AirPort Extreme. What I want to do is connect another AirPort Extreme to my main router and use it as a lab network. Basically I want the second AirPort Extreme to be on a different subnet. I don't even need the wireless part of it, I've turned it off. Is this possible? I'm trying to follow the Youtube video below but it is not working. Please Help.

By default, Apple uses the 10.0.1.2 to 10.0.1.200 range on their routers, so your "main" AirPort Extreme is already using that subnet.....unless you have changed the ranges or the values.

Verify by using AirPort Utility to check the Network Options for the main AirPort Extreme.

Assuming your "main" AirPort looks like the example above, then you would configure the second AirPort Extreme to use a different subnet......for example.....10.0.5.2 to 10.0.5.200.

Done. Now the second AirPort Extreme is on a different subnet.

You will have a Double NAT with this type of setup, but you can click to "ignore" the Double NAT notice so the AirPort will display a green light.

Awesome, thanks Bob. I'll try that. Would my devices connecting to the 2nd airport be able to get internet? Under the internet tab on the second router so I need to set it to static instead of DHCP?

Thanks

Sure

Simpler to just use DHCP. No need to do this unless you want to. You would have to have the "main" AirPort Extreme issue a static IP address to the second AirPort Extreme if you want to go the static route.

I just made the changes you suggested and it is working the way it's supposed to I think. I disabled wifi on my macbook and connected to the 2nd router using ethernet. I checked and I am getting an IP on the other subnet and I'm getting internet. Thanks so much for your help. My ultimate objective is to setup a Windows server 2012 domain controller connected to this second router and have that domain controller also handle DHCP and DNS for the devices physically plugged into the second airport extreme. Would that be possible?

Sorry, I can't help on Windows, much less Windows Server.

I understand. I think you may have gotten me there or most of the way there and I totally appreciate it. You've been a huge help. Thank You. When I get my domain controller setup I will reply here and let you know how it works.

Good luck! Post back if you need some tips on setting up a Static or Reserved IP address for the second AirPort to pick up from the first AirPort.
