How do I make my Mac Mini do bridging over wireless instead of NAT?
How do I use my Mac Mini to share its ethernet network connection over the wireless connection, but in a way that NAT is not used? In other words, how do I make my Mac Mini do bridging over the wireless connection?
Here is my network setup:
Cable Modem -> Router (IP 192.168.0.1)
Router connects to two desktop Macs:
Router -> Upstairs Mac (192.168.0.6)
Router -> Downstairs Mac (192.168.0.50)
I want to use the downstairs mac as a wireless access point. I have done this using Internet Sharing, which works fine *except* that devices on the wireless get a 10.0.0.* address. Computers on the 10.0.0.* net, like my laptop and iPhone, and cannot see the shared services of the upstairs mac, such as iTunes and iChat over Bonjour.
The problem seems to be that the mac with the wireless connection automatically uses NAT, and I can’t figure out how to make it just do bridging. I would like for devices that connect to the wireless to get a 192.168.0.* address, and be able to route across the mac mini to get IP addresses from the router by DHCP.
Can anyone tell me how to do that? I am perfectly comfortable with the command line, but am just not sure how to configure it.
