How do I configure Server DHCP for a shared-over-WiFi network connection?

Hey all,

Here's how my network is set up-

Comcast > Modem > DD-Wrt router >(Ethernet)> Mac Mini >(WiFi)> Macbook Pro, other devices.

I set the router to use the Mac Mini (with OS X Server) as the DHCP server, and I have the Mac Mini sharing the ethernet connection over WiFi.

The issue is that while my Macbook Pro can get an IP from the Mac Mini (as per DHCP settings), there's no internet connection. I'm not sure I even have the router IP set correctly, should it be the Mac Mini's IP or the router's IP?

MacBook Pro (13-inch, Mid 2012), OS X Mountain Lion (10.8.3)

I would normally use the router as the DHCP server but it should be possible to use your Mac mini as the DHCP server instead.

With regards to the WiFi, you would want to configure it in bridging mode, this will let WiFi clients and Ethernet clients be on the same subnet and the WiFi clients will then be able to request DHCP addresses from your server on Ethernet. This is the way I have my home network setup.

In the DHCP settings on your Mac mini server, you need to define the default gateway/router as being the IP address of your router. You also need to define valid DNS server addresses. If you running your own internal DNS server perhaps for Open Directory then this would be your internal DNS server address. The range of IP addresses you are issuing need to match the range being used internally by your router as does the subnet mask.
